Abstract
This Zenodo data entry is a documentation placeholder and diagnostic data release for the v_2025_04_18 0.5 degree gridded data released via ESGF.
This data is derived from CEDS v_2025_03_18 aggregate emissions release, which includes emissions data files by emission species (SO2, NOx, BC, OC, NH3, NMVOC, CO, CO2, CH4, N2O), country, and sector released here:
https://zenodo.org/records/15059443
This data set corrects spurious emissions in the CEDS v_2025_03_18 Gridded data 0.5 degree documented here:
https://zenodo.org/records/15001544
These corrections include:
1) significant corrections to seasonality for 2022 - 2023 across various sectors.
2) There are a few very small changes (in totals and spatial allocation) between 1961 - 2021 that correct an error in the previous release.
Species Sector Max glbl sect diff
CO IND -0.04%
CO2 ENE -2E-12
NOx IND and ENE -0.001%
(The relative differences are even smaller when total values across sectors are considered.)
For years before 1961, all files are identical to the previous release (v_2025_03_18 Gridded data 0.5 degree).
This data set can be accessed via ESGF, for detailed instructions on how to access and download, as well as data notes, see the README file attached.
The files released here include:
CEDS_v_2025_04_18_0.5_Gridded_README.txt (instructions for access on ESGF and data notes)
