Revision as of 18:27, 1 June 2023

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 14.2.0

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.

Feature Contributor(s) Model scope Ease of implementation Notes and References
Update transport tracer simulation for consistency with the tracer gridded component in GEOS Melissa Sulprizio (Harvard) TransportTracer simulation Medium
Move Aerosol_Mod module variables to State_Chm Lizzie Lundgren (Harvard) Aerosols Simple
TOMAS in GCHP Betty Croft (Dalhousie) TOMAS Simple
Bug fix for TOMAS sulfate production rates Betty Croft (Dalhousie) TOMAS Simple

Prioritized and in the queue

Features listed in this table are prioritized for integration into GEOS-Chem in the near future.
