The formula to convert perturbation potential temperature to total potential temperature in K can be found in the WRF users manual (p. The post-processing phase is an ideal candidate to start the migration to pyHWRF, as it is a small self contained component of the current system that needs to be modified to enable EMC’s method of running the tracker (continuously waiting for WRF output, versus a single instance at the end of the WRF forecast). WRF files aren't exactly CF compliant: you'll need a special parser for the timestamp, the coordinate names are a bit exotic and do not correspond to the dimension names, they contain so-called staggered variables (and their correponding coordinates), etc. I realize there are many scripts out there, so here's another resource to look at if you're learning python. This package provides over 30 diagnostic calculations, several interpolation routines, and utilities to help with plotting via cartopy, basemap, or PyNGL.
