Revision as of 14:55, 14 October 2011
On this page we list the priorities for ongoing GEOS-Chem model development. We also list the items that were once identified as priorities but have since been added to the standard mainline GEOS-Chem code.
List of priorities as of Oct 2011
This is list of planned GEOS-Chem model development items updated from the List of priorities identified at IGC5. The key model developer or model contact is identified for each item.
