GEOS-Chem model development priorities

This is a list of planned GEOS-Chem model development over the next two years, based on discussions and GEOS-Chem Working Group reports from the April 2009 GEOS-Chem Users' Meeting. The key model developer or model contact is identified for each item. Items are listed in rough order of decreasing readiness, although this can quickly change.

We count on user input to augment and prioritize this list, please contact your Working Group Chair or model scientist Daniel Jacob.
