Emissions Working Group

The purpose of this Working Group is to provide a forum to discuss current and new developments in GEOS-Chem associated with land-atmosphere and ocean-atmosphere sources, sinks, and fluxes of trace gases and aerosols.

All users interested in adding/updating the GEOS-Chem emissions inventories are encouraged to subscribe to the emissions email list (click on the link in the contact information section below).

Science findings from top-down studies that have implications for inventories used in GEOS-Chem (e.g., an inferred high or low bias or other such issue) can be compiled in this table. Please add any findings, either from your group or from other groups, that you feel the GEOS-Chem community should be aware of in using these inventories.

Recommended Default Emission Inventories

Emission inventories for standard full chemistry runs. Entries in BLACK are the recommended default emission inventories, entries in RED are alternate options, and entries in GREEN are inventories slated for inclusion in GEOS-Chem in the future. Regional inventories overwrite global inventories for particular locations (indicated in the table).

Year(s) show years for which the inventory is provided. In many cases annual scale factors are applied to extend the inventory to the past or present.

Please see our HEMCO data directories wiki page for information about how to download data files for each of the currently-available inventories.
