On this page we list the current priorities for GEOS-Chem development. This list was compiled by the user Working Groups at the last [http://acmg.seas.harvard.edu/geos/meetings/2017/index.html International GEOS-Chem Meeting (IGC8)] in May 2017 and will be continuously updated based on code readiness and input from the Working Groups and the Steering Committee.

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 [https://geos-chem.seas.harvard.edu/geos-working-groups Working Groups] and the [https://geos-chem.seas.harvard.edu/geos-steering-cmte Steering Committee]. For history of past releases see the [[GEOS-Chem_versions|GEOS-Chem Versions wiki page]].

Features listed in this table are actively being integrated into GEOS-Chem by the [https://geoschem.github.io/support-team.html 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.

Latest revision as of 20:55, 18 April 2024

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.

Merged and awaiting release

See the links below for items merged and awaiting release.

Mergeable at any time Version in development
GEOS-Chem no-diff-to-benchmark GEOS-Chem 14.4.0

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.
