-|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.
