Line 1: Line 1:
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]].
  
== Items that are now included in GEOS-Chem ==  
+
== Release schedule ==
  
Here we list model development priorities that have since been brought into the standard mainline GEOS-Chem code.  Each of these was identified a priority at the [http://acmg.seas.harvard.edu/geos/geos_meeting_2009.html 4th International GEOS-Chem Meeting] in 2009 (aka '''IGC4''') or the [http://acmg.seas.harvard.edu/geos/geos_meeting_2011.html 5th International GEOS-Chem GEOS-Chem Meeting] in 2011 (aka '''IGC5''').
+
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 ==
 +

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

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.
