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 Working Groups and the Steering Committee.
  
 
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.

=== 12.8.0 ===
  
=== Slated for v11-03 ===
+
<span style="color:darkorange">'''This version is currently in development. See [[GEOS-Chem_12#12.8.0|the ''GEOS-Chem 12'' wiki page]] for details.'''</span>
  
The following updates are now slated for inclusion into [[GEOS-Chem v11-03]]:

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)
Tomas Sherwen (York)
Shuting Zhai (UW)
Science
  • Delivered to GCST (Sep 2019)
  • Originally implemented in v11-02e and updated to 12.5.0 by Will Downs (GCST)
Fix incorrect rates in stratosphere for HOBr + SO3/HSO3 Seb Eastham (MIT) Science
Updates that WILL NOT AFFECT the full-chemistry simulation
Reduction of memory for HISTORY diagnostics with a species dimension Bob Yantosca (GCST) Structural

13.0.0

Feature Submitted by Type Notes and References
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

Priorities not yet assigned to a particular version
