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]].

Please see the [http://wiki.seas.harvard.edu/geos-chem/images/e/e1/GEOS-Chem_Release_Proposal.pdf GEOS-Chem Release Proposal] outlining the procedure and schedule for releasing GEOS-Chem versions.

+
== Feature integration in progress ==
  
This version will require a 1-month full-chemistry benchmark and 1-year full-chemistry and transport tracer benchmarks, with and without Luo wet deposition.
+
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.

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.
