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.

Priorities assigned to upcoming GEOS-Chem versions

12.4.0

This version is currently in development. See the GEOS-Chem 12 wiki page for details.

12.5.0

Feature Submitted by Type Status
New version of MAPL GMAO
Lizzie Lundgren (GCST)
