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 Minor version in development
- GEOS-Chem 13.4.0

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.

  • SF mechanism has been implemented and benchmarked in GEOS-Chem 12.0.0. This mechanism is of interest for those groups wanting fast global simulation of oxidation fields in GEOS-Chem simulations focused on aerosol microphysics.
  • The machine-learned chemical solver is still probably 12 months away from online implementation into GEOS-Chem.
