This is a list of planned GEOS-Chem model development items over the next two years, based on discussions and  [http://acmg.seas.harvard.edu/geos/geos_meeting_2009.html#wg_reports GEOS-Chem Working Group reports] from the April 2009 GEOS-Chem Users' Meeting. The key model developer or model contact is identified for each item. Items are listed in rough order of decreasing readiness, although this can quickly change.

'''''[[Main_Page|GEOS-Chem Main Page]] | [[GCHP_Main_Page|GCHP Main Page]]'''''
  
We count on user input to augment and prioritize this list, please contact your [http://acmg.seas.harvard.edu/geos/geos_working_groups.html Working Group Chair] or model scientist [mailto:djacob@fas.harvard.edu Daniel Jacob].
+
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]].

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.
