Line 1: Line 1:
This is a list of planned GEOS-Chem model development items over the next two years, based on discussions and  [http://acmg.seas.harvard.edu/geos/geos_meeting_2009.html#wg_reports GEOS-Chem Working Group reports] from the April 2009 GEOS-Chem Users' Meeting. The key model developer or model contact is identified for each item. Items are listed in rough order of decreasing readiness, although this can quickly change. 
+
'''''[[Main_Page|GEOS-Chem Main Page]] | [[GCHP_Main_Page|GCHP Main Page]]'''''
  
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].
+
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.
  
== Items that are now included in GEOS-Chem ==

Revision as of 15:50, 3 April 2020

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.

We also invite you to view our GEOS-Chem Support Team project management board on Trello.com, which shows the current GCST workflow.

Priorities assigned to upcoming GEOS-Chem versions

12.8.0

This version is currently in development. See the GEOS-Chem 12 wiki page for details.

12.9.0

This version will require 1-month and 1-year full-chemistry benchmarks.

Feature Submitted by Type Notes and References
Updates that WILL AFFECT the full-chemistry simulation
Updated halogen chemistry Xuan Wang (Harvard)

Updates that will NOT affect full-chemistry simulations
Retire the GNU Make build system in both GEOS-Chem Classic and GCHP and replace with CMake Liam Bindle (WashU) Structural
Retire the GEOS-Chem Unit Tester repository and move GEOS-Chem run directory creation to the GEOS-Chem source code repository Melissa Sulprizio (GCST) Structural
Make HEMCO a Git submodule in GEOS-Chem GCST Structural
Dynamic diagnostic array size allocation based on settings in HISTORY.rc Bob Yantosca (GCST) Structural
Features only affecting GCHP:
Retire the existing GCHP repository and replace with a new wrapper repository that uses ESMF as an external library and integrates GEOS-Chem and NASA/GMAO GEOS-ESM git repositories as git submodules Lizzie Lundgren (GCST) Structural
Separate HEMCO from GEOS-Chem to use as an ESMF gridded component in GCHP Lizzie Lundgren (GCST) Structural
