On this page we list the current priorities for GEOS-Chem development.  This list was compiled by the user Working Groups at the last International GEOS-Chem Meeting (IGC5) in May 2011 and has been continuously updated since based on code readiness and input from the Working Groups and the Steering Committee.

== List of priorities as of May 2012 ==
+
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 "Awaiting release" will be part of the next version release of GEOS-Chem and are actively being incorporated into the standard model and benchmarked. Other items are in different stages of readiness and will be included in future versions of the model.

== Release schedule ==
=== Awaiting release ===

 +
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.

|Diagnostic to archive XCO2, XCO, and XCH4
:By now we have done EDGAR 4, and now we are tackling the VOC speciation issue.  Then the next step is to incorporate several regional inventory datasets. My expertise is anthropogenic emission inventory development, so my efforts focus on how to include state-of-art research inventories in the GC model. I hope we can merge our efforts [with your efforts toward the [[Grid-independent GEOS-Chem#Emissions Component|Grid-independent Emissions Component]]] into one framework.

*We plan on delivering the [[Grid-independent GEOS-Chem#Chemistry Component|Chemistry Component]] to NASA/GMAO by June 1, 2012, which marks the end of Year 1 of the project.
 
*Development of the [[Grid-independent GEOS-Chem#Emissions Component|Emissions Component]] will be ongoing throughout Year 2 of the project.  Much of this work will be done by Christoph Keller (Harvard).  Our goal is to completely replace GEOS-Chem's legacy emissions routines with a modern emissions package that can be easily interfaced to an external GCM.

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 Minor version in development
