hey @pabloarosado! take a look at the changes I've made trying to improve the metadata and FASST and harmonize them across different charts we have. Also, it looks like we can get rid of this old dataset and compute annual averages ourselves based on the data that you update every couple of months to keep this chart up to date. I've added the relevant code for this on this PR too.

For each region, we calculate the mean temperature anomalies for 1961–1990 and for 1861–1890. The difference between these two means serves as the adjustment factor. This factor is applied uniformly to both the temperature anomalies and the confidence intervals to ensure that both the central values and the associated uncertainty bounds are correctly shifted relative to the new 1861–1890 baseline.

Hi @veronikasamborska1994 thanks for doing this harmonization! I had a look and left some minor suggestions. I think some of the baselines may not be totally clear (or at least in the comments). I can have a deeper look later, or please let me know if I misunderstood something.

Instead of creating a new dataset, I think it would be more convenient to create a new table inside the already existing sea_surface_temperature step. Then, in the climate_change_impacts step, instead of loading the two datasets sea_surface_temperature and sea_surface_temperature_annual, you could just load the former, an read the two tables. Does that make sense?

I think we can omit the "The" at the beginning of subtitles.

The deviation of the average land-sea surface temperature from the 1880-1900 mean, in degrees Celsius.
description_key:
- Temperature anomalies show how many degrees Celsius temperatures have changed compared to the 1880-1900 period.
- While 1861–1890 baseline period is commonly used to highlight the changes in temperature since pre-industrial times, here we use 1880–1900 instead, as monthly data on temperature anomalies in this dataset is only available from 1880.

"While a 1861-1890 baseline period..."

- This data is based on the GISS method which estimates temperatures in areas without data by using information from nearby locations within 1200 kilometers. This is especially useful in the Arctic and Antarctic, where measurements are sparse.
- Despite different approaches, GISS and other methods show similar global temperature trends.

We switch from using 1951-1980 to using 1880-1900 as our baseline to better show how temperatures have changed since pre-industrial times. For each region, we calculate the mean temperature anomalies for 1961–1990 and for 1880-1900. The difference between these two means serves as the adjustment factor. This factor is applied uniformly to both the temperature anomalies and the confidence intervals to ensure that both the central values and the associated uncertainty bounds are correctly shifted relative to the new 1880-1900 baseline.

I find this explanation a bit confusing: the original data used 1951-1980 as baseline, but to compute the adjustment factors you refer to the average of 1961-1990 (I haven't looked at the code yet, maybe it becomes clearer later).

I think in other charts we usually use "degrees Celsius" as unit, and "ºC" as short unit.

Shouldn't it be 1961-1990?

Again, just for clarity, mention that the new baseline starts in 1880.

We usually start description processing as bullet points (to clarify, it should be a string where each paragraph starts with "-").
