|Diurnal variability for NH3
+
|Henze group
+
|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.

Revision as of 13:18, 19 February 2019

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

12.3.0

This version is currently in development. See the GEOS-Chem 12 wiki page for details.

12.4.0

The items listed below are slated to be included in GEOS-Chem 12.4.0. This is a feature release which will be validated with a 1-month benchmark simulation and a 1-year benchmark simulation.

Feature Submitted by Type Status
Features affecting the full-chemistry simulation:
Grid-independent dust emissions (hourly) David Ridley (CARB, formerly MIT) Science
  • Data delivered to GCST (Jan 2019)
Grid-independent lightning NOx emissions (3-hourly) Lee Murray (Rochester) Science
  • Data delivered to GCST (Jan 2019)
Grid-independent biogenic emissions (hourly) Jintai Lin (PKU) Science
  • Data delivered to GCST (Jan 2019)
Grid-independent sea salt emissions (hourly) Jintai Lin (PKU) Science
  • Data delivered to GCST (Jan 2019)
Grid-independent soil NOx emissions (hourly) Jintai Lin (PKU) Science
  • Data delivered to GCST (Jan 2019)
