CEDS Release Notes

DOI (any CEDS release): 10.5281/zenodo.3592072

The DOI above will resolve to the latest release

First Full Release: December 23, 2019

DOI (CEDS v_2019-12-23): 10.5281/zenodo.3592073

Suggested Citation for this version of CEDS: Rachel Hoesly, Patrick O’Rourke, Caleb Braun, Leyang Feng, Steven J. Smith, Tyler Pitkanen, Jonathan J. Seibert, Linh Vu, Muwan Presley, Ryan Bolt, Ben Goldstein. (2019, December 23). JGCRI/CEDS: v-12-23-2019 (Version Dec-23-2019). Zenodo. http://doi.org/10.5281/zenodo.3592073

  • Fixed accounting of global shipping fuel consumption (this is largely fixing a bias introduced in a previous pre-release. However, in current version, some shipping emissions before the IEA data period are shifted from international shipping to domestic navigation. This does not substantially impact total emissions, but will impact the spatial distribution as compared to the CMIP6 data release.)

  • Corrections to addition of EIA historical coal consumption data for the USA

  • Corrections to addition of historical coal consumption data for Germany

  • Negative energy consumption data from historical UN statistics removed

  • Metadata tracking within the system now correctly removes duplicate entries

  • Users providing CEDS with total fuel consumption for a country can now choose if international shipping bunkers are included or not

  • Users providing CEDS with fuel consumption for a country can now choose if data should be normalized to CEDS default values or not after inclusion

  • Updated waste emissions calculation with fix to code and more realistic developed country urban burnt percentage parameter

  • Improved consistency of Korea BC and OC emissions with Korea national inventory addressing, in part, issue 5

(Also included are all the changes noted below.)

Pre-release Version: August 25, 2019

  • Updated waste emissions to use more realistic assumption for fraction burnt. Updated India per-capita waste generation to match recent literature estimate.

  • Fixed ordering of incorporation of user-added energy data

  • Improved consistency of unit conversions throughout code

  • India emissions now generally calibrated to GAINS emission factors

  • USA emissions now scaled to most recent EPA Trends data

  • Minimum transportation emission factor pathways updated

  • Aggregate industrial sector emissions seasonality changed to flat for all countries. Addresses issue with industrial seasonality

  • Other improvements

  • User guide additions

Pre-release Version: July 17, 2019

  • Code updates to facilitate use of newer versions of the BP energy statistics

  • BP 2019 statistics now used for energy data extension

  • Substantial speed-up of historical energy data processing in Module A, particularly on some cluster systems.

  • Wiki updated with instructions on how to download data files needed for gridding.

  • User guide additions.

Pre-release Version: June 7, 2019

  • Added capability for users to add exogenous historical energy data. This has been implemented for coal in the USA, UK, and Germany.

  • Hard and brown coal consumption by country extended back to 1950 (before IEA data years) using data from UN Energy statistics

  • Major changes to code structure with activity data for all years processed before any emissions-specific data processing.

  • Fuel allocation to sectors improved over early to mid 20th century (1920 - the earliest year of IEA data)

  • Other code improvements and fixes including BC spike in Netherlands, USA SO2 1960s overestimate

CMIP6 Data Release (data only) July 26, 2016

Historical emissions data as used for CMIP6, as described in Hoesly et al, Historical (1750–2014) anthropogenic emissions of reactive gases and aerosols from the Community Emissions Data System (CEDS). Geosci. Model Dev. 11, 369-408, 2018a.(https://www.geosci-model-dev.net/11/369/2018/gmd-11-369-2018.html)
