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 was updated in May 2018 following the release of v11-02 which included a number of these priorities. This list will be continuously updated based on code readiness and input from the Working Groups and the Steering Committee.

== Feature integration in progress ==
  
−
The items listed below are slated to be included in GEOS-Chem 12.3.0. This is a feature release which will be validated with a 1-month 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.

*For the sake of the documentation and the wiki I think we should replicate the standard benchmark year on our system, and then switch on the GFAS emissions instead of the GFED and then have the GFAS emissions distributed by hieight.  We can do that and then prepare some plots for the documentation.  Estimate summer 2018.

Latest revision as of 11:52, 19 July 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.
