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/2017/index.html International GEOS-Chem Meeting (IGC8)] in May 2017 and will be continuously updated 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.

The following updates are now slated for inclusion into [[GEOS-Chem v11-03]]:
+
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.

*'''''Lee Murray replied''''': "I would say 6-12 months to be safe, but the goal is to have it done by the end of summer 2018.  There will actually be very minimal updates to GEOS-Chem; most of the updates are to modify the GISS model to output MERRA2-like data, to facilitate integration with GCHP and future updates to the CTM."

Latest revision as of 14:54, 25 July 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.
