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 [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.

== Merged and awaiting release ==
  
== List of priorities as of May 2015 ==

See the links below for items merged and awaiting release.
  
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.

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.

Latest revision as of 18:24, 26 September 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
GEOS-Chem no-diff-to-benchmark GEOS-Chem 14.5.0

Feature integration in progress

Features listed in this table are actively being integrated into GEOS-Chem by the 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.

Feature Contributor(s) Model scope Ease of implementation Notes and References
New version of CEDS at 0.1 deg Dandan Zhang (WashU) Emissions Simple
Use USTAR read from GEOS instead of calculating from U10M and V10M Yuanjian Zhang (WashU) Emissions Simple
  • HEMCO PR #279
  • NOTE: WashU will recompute mass tuning factors for each met field & resolution (GCClassic)
New carbon simulation fixes in GC-Classic and GCHP GCST Carbon Medium
Fix obspack - not working in 14.4.0 Bob Yantosca (Harvard) Diagnostics Medium
Capture all trop and PBL height changes in budget diagnostics Chris Holmes (FSU)
Lizzie Lundgren (Harvard)
Diagnostics Medium
Make GC-Classic bit-for-bit reproducible upon restart Lizzie Lundgren (Harvard) GC-Classic Medium

Prioritized and in the queue

Features listed in this table are prioritized for integration into GEOS-Chem in the near future.

Feature Contributor(s) Model scope Ease of implementation Delivery status Notes and References
Retire CH4, CO2, tagCO simulations in favor of carbon simulation Melissa Sulprizio (Harvard) Carbon gases Simple
Correct the issue that injection height has been artifically decreased by HEMCO Yuanjian Zhang (WashU) Emissions Simple Delivered June 2024
Investigate potential performance gains of replacing the KPP Rosenbrock solver with the LSODE solver Bob Yantosca (Harvard) Chemistry Medium TBD
  • Will probably begin testing after 14.5.0 ships

Ready to go in

Features listed in this table are ready to go in but have either not been delivered or are not yet prioritized for integration into GEOS-Chem.
