On this page we list the current priorities for GEOS-Chem development. This list was compiled by the user Working Groups at the last International GEOS-Chem Meeting (IGC5) in May 2011 and has been continuously updated since based on code readiness and input from the Working Groups and the Steering Committee.
List of priorities as of Dec 2011
Items "Awaiting release" will be part of the next version release of GEOS-Chem and are actively being incorporated into the standard model and benchmarked. Other items are in different stages of readiness and will be prioritized for inclusion in future versions of the model.
