- **Data Latency:** Approximately 2 years + **Data Latency:** Updated annually - Surface methane (CH₄) emissions are derived from atmospheric measurements of methane and its ¹³C carbon isotope content. Different sources of methane contain different ratios of the two stable isotopologues, ¹²CH₄ and ¹³CH₄. This makes normally indistinguishable collocated sources of methane, say from agriculture and oil and gas exploration, distinguishable. The National Oceanic and Atmospheric Administration (NOAA) collects whole air samples from its global cooperative network of flasks (https://gml.noaa.gov/ccgg/about.html), which are then analyzed for methane and other trace gases. A subset of those flasks are also analyzed for ¹³C of methane in collaboration with the Institute of Arctic and Alpine Research at the University of Colorado Boulder. Scientists at the National Aeronautics and Space Administration (NASA) and NOAA used those measurements of methane and ¹³C of methane in conjunction with a model of atmospheric circulation to estimate emissions of methane separated by three source types, microbial, fossil and pyrogenic. Microbial emissions are produced by microbial decomposition of present-day organic matter, such as in wetlands, agricultural fields, livestock and landfills. Fossil emissions come from the breakdown of ancient carbonaceous matter deep underground, such as natural gas, coal bed methane, and small amounts of naturally occurring geologic seeps. Finally, pyrogenic emissions come from the burning of present-day organic matter, such as from wildfires and biofuels. These three sources of methane come with slightly different ¹³C content, and therefore can be separated given enough atmospheric measurements. This dataset presents monthly methane emissions from microbial, fossil and pyrogenic sources, along with a layer of total methane emissions from all three sources combined, at 1° resolution from 1999 to 2016. + Surface methane (CH₄) emissions are derived from atmospheric measurements of methane and its ¹³C carbon isotope content.

Careful quality checks are used to ensure data transformation has been performed correctly. - The emissions presented here are consistent with but not identical to the inversion result “CH₄+δ¹³CH₄” in [Basu et al. 2022](https://doi.org/10.5194/acp-22-15351-2022). Annual continental and global totals of these emissions are identical to those reported in [Basu et al. 2022](https://doi.org/10.5194/acp-22-15351-2022), while sub-continental and monthly patterns in these emissions are determined by the prior emissions used in [Basu et al. 2022](https://doi.org/10.5194/acp-22-15351-2022). + ## Scientific Details + Surface emissions were derived using an atmospheric inverse model described in [Basu et al. 2022](https://doi.org/10.5194/acp-22-15351-2022).

Several different inversions were performed by [Basu et al. 2022](https://doi.org/10.5194/acp-22-15351-2022), both as sensitivity tests (for example to test the impact of assumed sources signatures and atmospheric chemistry on the results) and to test specific hypotheses (for example to attribute the post-2007 growth in methane). The emissions shown here correspond to the “best case” simulation from [Basu et al. 2022](https://doi.org/10.5194/acp-22-15351-2022), labeled as “CH₄+δ¹³CH₄” in that publication. - - The atmospheric inverse model was run at 3° (longitude) x 2° (latitude) globally to estimate monthly surface emissions. The atmospheric inversion problem is under-constrained, and therefore inversely estimated emissions cannot be interpreted at the grid scale. Therefore, to present 1°x1° emission maps for the U.S. GHG Center, prior 1°x1° emissions were scaled to match the posterior continental and global totals for each source type and year. + The atmospheric inverse model was run at 3° (longitude) x 2° (latitude) globally to estimate monthly surface emissions.

+ **Data Latency:** Updated annually + + Methane is a relatively short-lived greenhouse gas responsible for about one third of greenhouse gas radiative forcing since pre-industrial times ([IPCC AR6, 2021](https://doi.org/10.1017/9781009157896)), making the reduction of atmospheric methane emissions an opportunity to slow near-term temperature rise. Satellites with instruments sensitive to methane have unique capabilities to pinpoint methane sources and potentially inform mitigation efforts. However, almost all of the instruments are in low Earth orbit and can only image an area of interest as frequently as once per day, at best. This dataset, in contrast, is from a geostationary satellite, which is able to capture imagery for the same location as often as every 5 minutes. Since geostationary satellites are positioned farther away from the Earth’s surface, they are only able to detect very large methane emission events, but provide the unique opportunity to track the full evolution of a methane release. + + Presented in the GHG Center is a collection of large methane release events detected by the U.S. Geostationary Operational Environmental Satellite 16 (GOES-16), starting in April 2019. Included are the methane plumes highlighted in [Watine-Guiu et al. 2023](https://doi.org/10.1073/pnas.2310797120), including releases originating from three different block valve stations during April-May 2019 along the El Encino La Laguna natural gas pipeline in Durango, Mexico, as well as several other detections across North America. Additional plumes will continue to be added as data becomes available. This data demonstrates the unique value of geostationary satellite instruments for detecting extreme and short-lived methane emission events, quantifying emissions from variable point sources, and precisely determining source locations. + +

GOES provides continuous 5–10-minute coverage of the Americas at 0.5–2 km nadir pixel resolution in 16 spectral bands. Shortwave infrared bands, SWIR band 5 (~1590-1630 nm) and 6 (~2220-2270 nm), which have respective nadir pixel resolutions of 1 km and 2 km, are used to track the full evolution of an extreme methane release. The multi band multi pass (MBMP) methane retrieval of [Varon et al. (2021)](https://doi.org/10.5194/amt-14-2771-2021) was adapted to infer methane column enhancements (mol/m²) from normalized reflectance differences between GOES bands 5 and 6 on different 5 minute scans. + + ## Key Publications + Watine-Guiu, M., Varon, D.

The GOSAT data is used in the model to inform total emission estimates, as well as wetland (the primary natural source of methane), and various human-related sources such as fossil fuel extraction, transport, agriculture, waste, and fires. An advanced mathematical approach is used with a global chemistry transport model to quantify annual CH₄ emissions and uncertainties. These estimates are expressed in teragrams of CH₄ per year (Tg/yr). Only the total and wetlands model-derived emissions are included in the US GHG Center.

These estimates are expressed in teragrams of CH₄ per year (Tg/year). Only the total and wetlands model-derived emissions are included in the US GHG Center. The source dataset contains emissions data for all other anthropogenic sources.

Updates include: + - Data added for 2010 - 2022 (previously, data was only provided for 2019) + - Change in spatial resolution from 1° x 1° to 4° (latitude) x 5°(longitude) + - Removal of uncertainty and priori data layers (priori model-estimated methane emissions for wetlands remains accessible via the [US GHG Center STAC Catalog](https://radiantearth.github.io/stac-browser/#/external/earth.gov/ghgcenter/api/stac/?.language=en)) + - Updated layer names and descriptions ## Dataset Accuracy - Data accuracy is determined by understanding the uncertainties in the model emissions. Bottom-up uncertainties are generally calculated by comparing how emissions attributions to each sector differ across studies, by comparing emission models and remote sensing data, and using expert opinion when uncertainties are especially challenging to estimate. Recent studies show that there could be larger than expected emissions from aquatic and fossil fuel sources. This means that current methane budgets estimated from both bottom-up and top-down models are either inaccurate in their allocations to existing sectors or that the atmospheric methane removal mechanisms (sinks) are not fully understood. For top-down uncertainties, recent studies also show that there can be considerable errors in the models used by remote sensing instruments to relate measurements to concentrations. Model transport errors can add additional uncertainty when inverting concentrations to fluxes. The flux inversion used for this top-down dataset reduces the impact of variability in the hydroxyl radical (OH), the main driver of methane removal, on methane emissions by jointly estimating OH and CH₄ emissions. A latitudinal correction is used to reduce the impacts of stratospheric chemistry and transport errors. Other systematic errors in model transport and chemistry were not characterized but it is not expected that these errors are significant. Additionally, the Bayesian approach used for this dataset enables the quantification of smoothing error, which can be a significant contributor to emission uncertainty, and reduces the potential for introducing additional uncertainty and biases when fluxes are projected back to emissions. Note that uncertainties are only appropriate at the 1-degree grid cell resolution. + Data accuracy is determined by understanding the uncertainties in the model emissions.

In a bottom-up approach, methane emissions from activity reports were projected through the GEOS-Chem global chemistry transport model to obtain the expected atmospheric concentrations. In a top-down approach, observed atmospheric methane concentrations from the GOSAT satellite are compared with those modeled from reports. An analytic Bayesian inversion approach is used to determine the methane flux on a 2 x 2.5 degree grid based on the differences between the two concentrations (bottom-up vs top-down). Analytic Jacobian matrices relating emissions to concentrations are derived from the GEOS-Chem model and used to calculate the prior and posterior flux error covariance. Methane fluxes are then linearly projected to emissions by sector at 1 degree resolution. The derivation used to project top-down fluxes back to emissions by region is described in [Cusworth et al. (2021)](https://doi.org/10.1038/s43247-021-00312-6). This GOSAT-based Top-down CH₄ Emissions dataset includes the total prior and posterior CH₄ emissions, wetland prior and posterior CH₄ emissions and associated uncertainties. More information is located in the [source dataset document](https://zenodo.org/record/8306874). + These wetland and anthropogenic fluxes, derived using atmospheric concentration data from the GOSAT model, demonstrate that wetlands are a primary driver of atmospheric methane increases from 2010 through 2022. In particular, substantial growth of both (wetland emissions and atmospheric methane) during 2019 and 2020, occurred as a result of increased inundation of African wetlands. Anthropogenic emissions also play a role in increasing atmospheric methane with these data pointing towards livestock emissions a likely driver. These results are published in [Qu et al. 2024](https://doi.org/10.1073/pnas.2402730121). ## Key Publications + Qu, Z., Jacob, D. J., Bloom, A. A., Worden, J. R., Parker, R. J., & Boesch, H. (2024).

Yet the sources of methane are not as well understood as CO₂, and NASA scientists are responding to that challenge by expanding missions and putting instruments to work in new ways. + + Two key technologies have made recent steps to meet the need for methane measurements. The Earth Surface Mineral Dust Source Investigation (EMIT) project is expanding its methane detection from space, and Airborne Visible/Infrared Imaging Spectrometer (AVIRIS) test flights are helping to improve scientific understanding of sources of methane. + + + + + + ## EMIT Expands Operations with a Renewed Focus on Methane + EMIT is a NASA instrument aboard the International Space Station. It was initially designed to measure the effects of mineral dust on the climate, but this versatile instrument has many capabilities, including detection of methane plumes from large emission events. Now [the EMIT mission will be extended for an additional three years](https://www.nasa.gov/missions/emit/nasas-emit-will-explore-diverse-science-questions-on-extended-mission/), with methane observations as one of its primary focus areas. + +

+ instrument in space over distant view of earth and black space + + The Earth Surface Mineral Dust Source Investigation, or EMIT, instrument was installed on the port side of the International Space Station's truss structure in July 2022. EMIT began as a mineral dust source observation experiment, though the mission has recently been extended for three years, enabling it to focus on detecting methane emissions. + +
+ + “The extended mission is particularly exciting,” said Dr. Andrew Thorpe, a Research Technologist at NASA’s Jet Propulsion Laboratory. Initially, EMIT only took measurements over parts of the world that produced large amounts of dust, like deserts. Coincidentally, some of these desert regions also contained large methane plumes, such as emissions from oil and gas operations in the Middle East. EMIT also detected large methane plumes coming from landfills within arid regions. “But we want to see beyond that,” said Thorpe. “EMIT will soon have near global coverage, and that’s tremendous.” + + This work is particularly beneficial because in some cases methane leaks can be repaired. Rapid detection of leaks can help facility operators, stakeholders, and decision-makers respond to large methane emissions events, thereby preventing further pollution, protecting nearby workers and communities, and supporting more efficient facility operation. + + Collecting data is an important step in understanding methane emissions, but to enable usability of the data, it must then be shared in ways that are easy to access and understand. + + To that end, an updated data viewer developed by the U.S. Greenhouse Gas Center (US GHG Center) allows users to interact with a global map of large, point-source methane plumes. Users can now trace EMIT observation passes over time, quantify plumes within a selected geographic region, and use a new point-and-click tool to measure plume size in miles or kilometers. +
+
+ +
+ +
+
+ + + + ## AVIRIS-3 Takes Flight to Spot Methane Sources + Aircraft-based measurements are another tool in methane detection, using a similar technology as EMIT, but on a more localized scale. “They can see smaller emissions,” said Thorpe, and because aircraft-based instruments cover a smaller area, they can produce higher resolution measurements and fill gaps in satellite data where overpasses are less frequent. + + The [AVIRIS-3](https://airbornescience.jpl.nasa.gov/instruments/aviris-3) instrument is the third generation of Airborne Visible/Infrared Imaging Spectrometers, and it can be flown on a variety of aircraft. Two recent collaborative airborne projects examined methane emissions from different geographic regions and sources. + + The first of these collaborations was a [two-week research effort](https://csl.noaa.gov/groups/csl3/measurements/2024ammbec/), joined by NASA, marking the launch of NOAA’s four-year [AiRMAPS](https://csl.noaa.gov/projects/airmaps/) (Airborne and Remote sensing Methane and Air Pollutant Surveys) initiative. Aboard research aircraft, NOAA scientists used direct air sampling to measure the total amount of methane in the air, while NASA’s AVIRIS-3 mapped methane concentrations across the study area to pinpoint the sources of methane. The flights, which were supported by the Colorado Department of Public Health and Environment, identified a number of large methane plumes which may be connected to sources like agriculture and landfills. + + "The state of Colorado has been a leader in managing methane emissions," said Steven Brown, Tropospheric Chemistry Program Leader with NOAA’s Chemical Sciences Laboratory. "The tiered observing system deployed this summer, including satellite remote sensing, AVIRIS flights, airborne in-situ measurements and ground based observations, will provide powerful new data to assess current methane emissions inventories for Colorado and other NOAA and NASA partners at the state level." + + Another AVIRIS-3 demonstration project measured methane plumes over the Gulf of Mexico. During a 12-day campaign, methane emissions from drilling platforms were measured by three different methods: by ship, by satellite, and from an AVIRIS-equipped aircraft. Detection of emissions over open water has historically been more challenging for satellite-based observations alone, so by leveraging different observation technologies and new methods, researchers are able to collect and validate data over wider geographic ranges. + + Dr. Ryan Stauffer, a research scientist from NASA’s Goddard Space Flight Center, was one of the scientists who took part in the field research. “What we did out there was very cool,” he said. “The newest instruments are getting better and better data. We’re learning more and more.” + + The AVIRIS-3 instrument was flown aboard a series of NASA [SCOAPE](https://www-air.larc.nasa.gov/missions/scoape/index.html) (Satellite Coastal and Oceanic Atmospheric Pollution Experiment) flights, in coordination with the U.S. Bureau of Ocean Energy Management. The goal of the project was “to understand all we can about oil and gas operations in the Gulf of Mexico,” said Stauffer. + +

+ + The science teams observed around 60 offshore platforms and identified “dozens of plumes,” according to Stauffer. “Finding and sharing information on methane leaks is low-hanging fruit in terms of supporting solutions, and in terms of reducing emissions,” he explained. + + Localized measurements are particularly useful for facility managers and stakeholders, in part because methane plumes can be spotted in real time during flyovers, allowing for swift action to remedy leaks or repair malfunctioning equipment.

It was the first time that methane emissions from an individual facility had been observed from space – and it marked the beginning of a wave of innovation in remote-sensing methane detection technologies that can provide actionable data. + + Now, the Environmental Protection Agency is leveraging those innovations through a new program designed to identify abnormally large methane emissions from oil and natural gas facilities for prompt investigation. + + + + + +

+ + + + These large methane emissions events are commonly called “super emitters.” They can result from planned maintenance or other routine operations but are frequently caused by improperly operating control devices or malfunctions. Leaking equipment, hatches left open on storage tanks, and malfunctioning flares and other devices all can cause super emitters. + + Recent studies have found that as much as 50% of the methane emissions from oil and natural gas operations in the U.S. come from a small number of high-emitting sources. These events can be intermittent and can occur at any site, which makes it difficult both to predict them – and to detect them through regular monitoring surveys using traditional leak detection equipment such as optical gas imaging or hand-held flame ion detectors known as “sniffers.” + + Advanced remote-sensing technologies are making super-emitters easier to find. So, as part of its recent [rule to reduce methane emissions from oil and natural gas operations](https://www.federalregister.gov/documents/2024/03/08/2024-00366/standards-of-performance-for-new-reconstructed-and-modified-sources-and-emissions-guidelines-for), the EPA established a program specifically designed to help identify these events and quickly notify owners and operators. Under the new Super Emitter Program, technology providers may apply to the EPA to have their remote methane detection technologies approved for use in the program. These include technologies that can be carried on satellites and mobile platforms, such as drones, aircraft, and other vehicles. + + Separately, independent third parties may seek EPA certification to use the approved technologies to identify potential super emitters, which the agency has defined as methane leaks or releases with an emissions rate of 100 kilograms per hour or higher, and report those to the EPA, along with required information related to the event. + + Certified third parties will have a maximum of 15 days after detecting a super-emitter event to report it to the EPA. After reviewing the report for completeness and accuracy, the EPA will notify the owner/operator, who must begin required investigations within five days. These investigations would normally include reviewing maintenance activities, reviewing control device monitoring data, and screening the entire site with traditional leak detection methods. Owners/operators must report the result of their investigations to the EPA within 15 days of receiving the notification. If the source of the emissions is covered by emissions control requirements under the EPA’s “methane rule,” owners/operators must take steps to mitigate the emissions. The EPA will post super-emitter reports on its [Super Emitter website](https://www.epa.gov/compliance/methane-super-emitter-program-owners-operators). +

About Methane

+ + Methane is a greenhouse gas emitted by a complex mix of natural sources and human activities. Although it is shorter-lived than carbon dioxide in the atmosphere, the structure of methane molecules makes the chemical compound particularly powerful at trapping heat: the comparative impact of methane is 28 times greater than carbon dioxide over a 100-year period. These attributes make methane an attractive focus for efforts to research and reduce emissions, which can help to limit rising temperatures, improve air quality, and support operational efficiency within some industrial sectors. + +
+
+ + To meet the growing need for information, innovative new observations and coordination across public and private data providers are enhancing trust and transparency in methane data. Explore below to learn how researchers and data providers are working to understand emissions around the world and support local scale views of methane sources. +

The U.S. Greenhouse Gas Center portal houses several complementary resources to identify sources and estimated levels of atmospheric methane. + + About a third of methane emissions are from wetlands, generated naturally as a byproduct of microbes in oxygen-depleted soils. That microscopic level is where researcher Ben Poulter, of NASA’s Goddard Space Flight Center in Greenbelt, Maryland, started building the NASA Wetlands Methane Emissions Model, which incorporates satellite observations, measurements from field campaigns such as [BlueFlux](https://science.nasa.gov/science-research/earth-science/nasas-blueflux-campaign-supports-blue-carbon-management-in-south-florida/), and information about weather patterns. + + “We rely on understanding the mechanics of how microbes produce methane, and how that’s related to temperature, moisture, soil type, etc.,” Poulter said. “The goal is to help us understand how much methane is coming from global wetlands, and then use that information to look at whether changes in temperature are influencing that trend.” + +
+ trees with green leaves and many roots at base extending into soil + + Wetlands, like this mangrove forest in south Florida that was one of the sites of NASA’s Blue Flux field campaign, are a major natural source of methane emissions, generated by microbes in the water-logged and oxygen depleted soils. Scientists use a variety of tools to measure how these sources contribute to the global methane budget, including the NASA Wetland Methane Emissions Model available in the U.S. Greenhouse Gas Center. + +
+ + In the tropics, microbes become more active when temperatures are higher, and wetter conditions lead to more flooding and therefore more oxygen-depleted soils. In the Arctic, thawing permafrost frees up buried carbon that had previously been frozen in place and inaccessible to microbes. + + If wetlands are producing more methane as temperatures rise, that increase in emissions could dampen some of the progress made by reducing emissions from sources related to human activities. + + “I think it emphasizes the need to take an Earth system perspective on the global methane budget,” Poulter said. “There are immediate opportunities to address anthropogenic sources, but at the same time, now that we’re seeing farther-reaching temperature impacts on Earth systems, we need to keep track of the more natural sources of greenhouse gasses as well.” + +
+ + + This animation produced by NASA’s Wetland Methane Emissions Model shows concentrated methane sources from tropical and high latitude ecosystems. The model is regularly used to simulate the impact of wetlands and other method sources on atmospheric methane concentrations, compare against satellite and airborne data, and to improve understanding and prediction of wetland emissions. + +
+ + While the wetlands methane model starts, literally, from the ground up, other models – such as NOAA’s Carbon Tracker Methane Emissions – take the opposite approach. This methane tracker ingests atmospheric greenhouse gas concentration data along with other conditions like winds and weather and then estimates emissions, said Lori Bruhwiler, a physical scientist with NOAA’s Global Monitoring Laboratory in Boulder, Colorado. + + “We’re not trying to forecast the future concentrations of methane, instead these numerical techniques go back in time to find the distribution and fluxes of methane sources over the past several decades,” Bruhwiler said. + + NOAA also has a tool to track carbon dioxide (CO₂) emissions, but methane is such a different compound that it needs its own specific model, she said. Once in the atmosphere, CO2 is very stable and can last for 300 to 1,000 years. Methane, on the other hand, reacts with other gasses in the atmosphere and is removed by atmospheric chemistry, resulting in an atmospheric half-life of about 10 years. + + “That’s why there’s so much attention on methane,” Bruhwiler said. “If emissions decrease, and what’s already there is removed within 10 years, there can be a near term benefit of avoided temperature increases.” + + This effort, however, is complicated by the numerous sources of methane. Emissions are the result of unintentional oil and gas pipeline or coal mine leaks, agricultural sources (livestock and rice), landfills, sewage waste, reservoirs, wildfires, wetlands and permafrost thawing – it’s a challenge to determine the budget of what is from natural sources, and what is human-caused, she said. + +

Wildfires are a natural source of pyrogenic methane emissions which contribute to global atmospheric concentrations of the gas. + +
+ + While NOAA’s model uses information from a global network of surface sampling sites, other models take a space-based vantage point and utilize satellite observations to fill in gaps in data. NASA's Carbon Monitoring System Flux team in partnership with Harvard University uses measurements from Japan’s Greenhouse Gases Observing Satellite, or GOSAT, to derive spatially-resolved estimates of total global methane emissions, as well as source-specific estimates for wetlands and various human-related emissions. + + Quantifying different forms of methane to help decipher their source is critically important to understand global trends in methane. As researchers develop innovative and complementary models and methods of observation, they gain new insights into the complex balance of natural and human-caused sources of methane. + + Findings also contribute to cooperative international research efforts like the Global Carbon Project’s [Global Methane Budget](https://www.globalcarbonproject.org/methanebudget/), and allow decision-makers to track progress of initiatives including the [Global Methane Pledge](https://www.globalmethanepledge.org/), in which more than 150 countries committed to reducing methane emissions by 30 percent of 2020 levels by the end of the decade. + +

Methane data from [GHGSat](https://www.ghgsat.com/en/), a commercial data provider specializing in high-resolution remote sensing of greenhouse gasses, was evaluated and verified by NASA’s Commercial Small Dataset Acquisition program, receiving approval in July 2024.

An initial set of detections using Tanager-1 were released on Carbon Mapper’s data portal in November 2024, adding to their public emissions data from airborne surveys as well as NASA’s EMIT instrument. + + + + +

+
+ + + + The NIST-led effort to establish consensus standards for remote sensing of point sources contributes to the broader ecosystem of methane observations, including efforts to improve emissions quantification across multiple scales. + + Earlier this year, a new satellite dedicated to tracking methane emissions took to orbit. Launched in March 2024, the [MethaneSAT](https://www.methanesat.org/) project is led by the nonprofit Environmental Defense Fund and supported by experts from private organizations including Harvard and Google. + + Whereas a global mapper can see images of a broad area to learn about large scale emissions, and “point source” detectors focus on a much smaller field of view for high-resolution plume observations, MethaneSAT looks at an intermediate spatial scale level that includes point source contributions to wider area emissions. + + The combination of these new observations from space-based instruments offers a more complete view of methane emissions than ever before. + + {/* Professor Steve Wofsy is a Harvard scientist working on the MethaneSAT project. Of the surge of new space-based instruments, he said, “With a global mapper, you can see images of a broad area that can be used to learn about large scale emissions. Other missions are what we call ‘point source’ detectors; they have a much smaller field of view and can see plumes. MethaneSAT bridges the gap by looking at the region, not the whole globe.” */} + + + + + +

+
+
+ +{/* + + The combination of these new observations offers a more complete view of methane emissions than ever before, explained Wofsy. “Any one of these independent approaches can work really well. All taken together, they have the capability of providing a comprehensive global dataset to understand methane emissions.” + + */} + + + + ## Setting the Stage for Operational Data and Services + New measurements offer increased opportunities for monitoring and reporting methane emissions. In a general sense, more data is better; however, proper context is required to optimize use of all of these datasets. + + Observations from different platforms are characterized by subtle differences in spatial resolution and sensitivity to atmospheric factors like clouds and particles that can influence measurement quality. Interpreting the data also involves assumptions about wind direction and speed which transport the methane from its point source. Annmarie Eldering, an environmental engineer at NIST, said this is where the challenge lies. + + + + + + + + + + + + + This is the focus of a methane intercomparison project led by Eldering. NIST is working with scientists across a range of government, nonprofit, and commercial data providers, including EMIT, GHGSat, Carbon Mapper, and MethaneSAT, to understand and foster alignment in how methane plume detection and quantification with remote sensing is performed. + + This effort includes defining common language used to describe data, establishing consensus for data formatting and validation, and collaboratively developing and documenting intercomparison techniques. + + “As the volume of available methane data grows at exponential rates, this standardization is critical to enable trustworthiness and usability,” said Eldering. + + As the methane intercomparison project progresses, Eldering hopes it will lead to a transparency portal for data providers, where science teams can prepare and share material to show steps in their analysis process and a wider working group can then analyze a benchmark set of measurement data to try to replicate the analysis. This type of analysis and complete documentation is key to achieving consensus standards. + + The transparency of established standards allows users to work with data with the knowledge that providers have followed consensus protocols, a particular challenge when using private space observations whose algorithms are often proprietary and not publicly disclosed. + + Common language, formatting and validation of methane measurements will make data products more accessible and useful to the broader community, and may support interoperable use of multiple satellite datasets to provide more comprehensive observations. These efforts benefit both users of GHG information by helping them understand the benefits of different products and private data and service providers by enabling them to serve customers more efficiently. + + + + + + **Author:** + *Emily Bell, NASA Goddard Space Flight Center* + + + + + + ## Resources for Data Users + - Detailed dataset information: EMIT Methane Point Source Plume Complexes + - Information on GHGSat data available through NASA: CSDA Vendor - GHGSat + - Visit the Carbon Mapper data portal + - Visit the MethaneSAT data portal + + + + + + ## References + Atmospheric Chemistry and Physics (2022), [Quantifying methane emissions from the global scale down to point sources using satellite observations of atmospheric methane](https://acp.copernicus.org/articles/22/9617/2022/acp-22-9617-2022.pdf) + + diff --git a/stories/nist-urban-testbeds.stories.mdx b/stories/nist-urban-testbeds.stories.mdx index e6f64d280..22e843345 100644 --- a/stories/nist-urban-testbeds.stories.mdx +++ b/stories/nist-urban-testbeds.stories.mdx @@ -13,13 +13,14 @@ pubDate: 2024-09-20 taxonomy: - name: Topics values: - - Urban - Anthropogenic Emissions + - Methane + - Urban - name: Gas values: + - CO - CO₂ - CH₄ - - CO --- import Quote from "./components/quote"; diff --git a/stories/tracking-greenhouse-gas-cycles.stories.mdx b/stories/tracking-greenhouse-gas-cycles.stories.mdx index a995b429e..52597e326 100644 --- a/stories/tracking-greenhouse-gas-cycles.stories.mdx +++ b/stories/tracking-greenhouse-gas-cycles.stories.mdx @@ -12,11 +12,12 @@ pubDate: 2023-08-30 taxonomy: - name: Topics values: + - Methane - Natural Emissions and Sinks - name: Gas values: - - CO₂ - CH₄ + - CO₂ --- diff --git a/stories/urban.stories.mdx b/stories/urban.stories.mdx index fe737d17f..37250c876 100644 --- a/stories/urban.stories.mdx +++ b/stories/urban.stories.mdx @@ -2,20 +2,6 @@ id: "urban" name: "Topic: Urban Emissions" isHidden: true -# media: -# src: ::file ./media/total-methane-2020.png -# alt: Map of total U.S. gridded methane emissions in the year 2020 -# author: -# name: Environmental Protection Agency -# url: "https://www.epa.gov" -# pubDate: 2024-09-20 -# taxonomy: -# - name: Topics -# values: -# - Anthropogenic Emissions -# - name: Gas -# values: -# - CH₄ --- import Cmp from "./urban/component" diff --git a/stories/us-methane-sources.stories.mdx b/stories/us-methane-sources.stories.mdx index e10c70050..02b539cab 100644 --- a/stories/us-methane-sources.stories.mdx +++ b/stories/us-methane-sources.stories.mdx @@ -13,6 +13,7 @@ taxonomy: - name: Topics values: - Anthropogenic Emissions + - Methane - name: Gas values: - CH₄ diff --git a/stories/vulcan.stories.mdx b/stories/vulcan.stories.mdx index 8b24b8308..ea9efc1a1 100644 --- a/stories/vulcan.stories.mdx +++ b/stories/vulcan.stories.mdx @@ -14,8 +14,8 @@ isHidden: false taxonomy: - name: Topics values: - - Urban - Anthropogenic Emissions + - Urban - name: Gas values: - CO₂ diff --git a/veda.config.js b/veda.config.js index 9a54d3286..e751b0eeb 100644 --- a/veda.config.js +++ b/veda.config.js @@ -90,7 +90,7 @@ module.exports = { "This dashboard is for exploring key datasets that provide insight into greenhouse gas sources, sinks, emissions, fluxes, and events.", // Temporary Banner Text/URL/expiry tempBanner: - "Read the new data insight on using EMIT and AVIRIS-3 for monitoring large methane emission events.", + "Read the new story on using EMIT and AVIRIS-3 for monitoring large methane emission events.", tempBannerUrl: "stories/emit-and-aviris-3", tempBannerExpires:
