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]].
  
== List of priorities from IGC8 ==
+
== Release schedule ==
  
The items listed below are in different stages of readiness and will be included in future versions of the model.
+
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.  
  
=== Slated for v11-03 ===
+
== Merged and awaiting release ==
  
The following updates are now slated for inclusion into [[GEOS-Chem v11-03]]:

== 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.

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.
