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/2013/index.html International GEOS-Chem Meeting (IGC6)] in May 2013 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]].

*'''''NOTE:''''' The GEOS-5 "FP" product (aka GEOS-5.11.0) is what we will use for the 0.25&deg; x 0.3125&deg; nested simulations.  To run the nested simulations (the 2 items listed below), we also must be able to run the global simulations with this met data product in order to save out transport boundary conditons.

== Feature integration in progress ==

=== 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
