View source for Emissions Working Group

<u>The purpose of this Working Group</u> 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 [[#Primary Working Group Contacts|contact information section]] below).

== Top-down Findings Germane to GEOS-Chem Inventories (please add yours!) ==

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 [[Inventory Findings|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.
