Revision as of 21:42, 23 November 2016
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 (IGC7) in May 2015 and has been continuously updated since based on code readiness and input from the Working Groups and the Steering Committee.
We also invite you to view our GEOS-Chem Support Team project management board on Trello.com, which shows the current GCST workflow.

List of priorities as of Nov 2016
The items listed below are in different stages of readiness and will be included in future versions of the model.
Awaiting release
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. More information on those items can be obtained on the GEOS-Chem v11-01 wiki page.
