GEOS-Chem Main Page | GCHP Main Page
On this page we list the current priorities for GEOS-Chem development. This list is 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.
