Revision as of 22:34, 16 November 2017
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 (IGC8) in May 2017 and will be continuously updated 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.
