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/2015/index.html International GEOS-Chem Meeting (IGC7)] in May 2015 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 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.

Items "Awaiting release" will be part of the next version release of GEOS-Chem and are actively being incorporated into the standard model and benchmarked. Other items are in different stages of readiness and will be included in future versions of the model.

*''Update 30 July 2015:'' A moisture signature is observed in CO2 concentrations during carbon simulations with zero emissions and constant 370 ppm initial conditions. The moisture signature is expected for wet mixing ratio (v/v total air) but not dry mixing ratio (v/v dry air). This issue is currently under investigation.

:I've incorporated both the metal catalyzed chemistry and the sulfate isotopes into v10. The metal catalyzed chemistry is much slower than it is when run in v8 and v9. I still have not yet figured out why. I'm not comfortable adding this into the standard model until I figure it out. The emissions are quite different in v10 because of HEMCO, and metal catalyzed chemistry is very sensitive to emissions of primary anthropogenic sulfate, so that's my current hypothesis for the difference. I will probably not get back to debugging this until late October.

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
