On this page we list the priorities for ongoing GEOS-Chem model development. We also list the items that were once identified as priorities but have since been added to the standard mainline GEOS-Chem code.
+
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 as of Dec 2011 ==
+
== Merged and awaiting release ==
  
−
This is list of planned GEOS-Chem model development items updated from the [[GEOS-Chem model development priorities#List of priorities identified at IGC5|List of priorities identified at IGC5]]. The key model developer or model contact is identified for each item.  
+
See the links below for items merged and awaiting release.

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].

−
=== Ready to go in ===
+
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.

Revision as of 18:08, 21 March 2024

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.

Merged and awaiting release

See the links below for items merged and awaiting release.

Mergeable at any time Version in development
