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).
