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/2015/index.html International GEOS-Chem Meeting (IGC7)] in May 2015 and has been continuously updated since 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]].
  
We also invite you to view our [https://trello.com/board/geos-chem-support-team/4fe36668fc79a1d3540ba80b GEOS-Chem Support Team project management board on Trello.com], which shows the current GCST workflow.

== Merged and awaiting release ==
  
== List of priorities as of May 2015 ==

See the links below for items merged and awaiting release.
  
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.

Features listed in this table are actively being integrated into GEOS-Chem by the [https://geoschem.github.io/support-team.html 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.

*Included in [[GEOS-Chem v11-01#v11-01a|v11-01a]] and approved on 07 Jul 2015
+
*''Update 30 July 2015:'' A moisture signature is observed in CO2 concentrations during carbon simulations with zero emissions and constant 370 ppm initial conditions. The moisture signature is expected for wet mixing ratio (v/v total air) but not dry mixing ratio (v/v dry air). This issue is currently under investigation.
