|Science

|Daven Henze wrote:
+
*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.

*"I would say 6-12 months to be safe, but the goal is to have it done by the end of summer 2018.  There will actually be very minimal updates to GEOS-Chem; most of the updates are to modify the GISS model to output MERRA2-like data, to facilitate integration with GCHP and future updates to the CTM."

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

13.0.0

This version is now under development. Please see the GEOS-Chem 13 wiki page for more details.

Priorities not yet assigned to a particular version

The following items have been identified as priorities for GEOS-Chem, but have not yet been assigned to a particular GEOS-Chem version.
