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 [http://acmg.seas.harvard.edu/geos/geos_working_groups.html Working Groups] and the [http://acmg.seas.harvard.edu/geos/geos_steering_cmte.html Steering Committee]. For history of past releases see the [[GEOS-Chem_versions|GEOS-Chem Versions wiki page]].
  
We also invite you to view our [https://trello.com/board/geos-chem-support-team/4fe36668fc79a1d3540ba80b GEOS-Chem Support Team project management board on Trello.com], which shows the current GCST workflow.

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. For history of past releases see the GEOS-Chem Versions wiki page.

Release schedule

Please see the GEOS-Chem Release Proposal outlining the procedure and schedule for releasing GEOS-Chem versions.

Merged and awaiting release

See the links below for items merged and awaiting release.

Patch version in development Major version in development
- GEOS-Chem 14.0.0

Feature integration in progress

Features listed in this table are actively being integrated into GEOS-Chem by the GEOS-Chem Support Team. In addition, we continuously implement structural updates in the model to maintain and develop coupling with other models including GEOS, CESM, and the model adjoint.
