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.

== Feature integration in progress ==
  
−
The items listed below are slated to be included in GEOS-Chem 12.2.0. This is a feature release which will be benchmarked with a 1-month benchmark simulation and a 1-year Rn-Pb-Be benchmark simulation.
+
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.

*The FORTRAN code for implementing NH3 emissions diurnal variability is fairly straightforward.  However, it involves calculation of some quantities that depend upon met fields in the future, and we’re unsure of how to accomplish this in a robust and elegant manner. 
+
 
−
*In particular, we need to know the aerodynamic resistance and surface temperature at every emission time step over the course of a time period X, where X is the time resolution of the NH3 livestock emissions inventory being used.  This is typically monthly, but I could foresee future inventories having higher resolution, so maybe we want to consider this more generically. 
+
−
*One approach would be to pre-process this quantity at high resolution for all years, as is currently being done e.g. for dust emissions.  Another would be to add code to read in this information from met files online, but this would add some i/o to the model.

Revision as of 14:19, 25 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.
