Latest revision as of 20:20, 24 June 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 soil NOx parameterization Yi Wang (U. Iowa)
Jun Wang (U. Iowa) 		Emissions Medium
Horizontal flux regridding fix in MAPL Tom Clune (GMAO) GCHP Medium
Cloud-J 7.7.2 for greater flexibility in external models Lizzie Lundgren (Harvard) Photolysis Medium
GCHP run directory improvements for mass flux, stretched grid, and GEOS-IT runs Lizzie Lundgren (Harvard) GCHP Medium
Fixes for GEOS-Chem 14.4 in CESM Haipeng Lin (Harvard)
Lizzie Lundgren (Harvard) 		CESM 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
ALK4 & R4N2 chemistry Jared Brewer (UMN) Chemistry TBD Delivered
New version of CEDS at 0.1 deg Dandan Zhang (WashU) Emissions Simple Delivered June 2024
Remove differences in GC-Classic due to HEMCO reading REAL8 restart as REAL4 Lizzie Lundgren (Harvard) GC-Classic Medium

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.
