Hopefully this is an easy one: how can I decouple RTHRATEN, the total theta tendency due to radiation, from mass using wrf output variables? <a href="http://forum.wrfforum.com/viewtopic.php?f=37&t=129">Unofficial</a> <a href="http://www.atmos.washington.edu/~scavallo/wrf_thermo.pdf">documentation</a> online suggests division by MUT = MU + MUB, but MUT is a total column mass (maybe it wasn't in 2008 when those documents were written) whereas the theta tendency is 4-dimensional. Currently, I'm dividing RTHRATEN at each (lat,lon,eta) point by MUT(lat,lon). Can someone confirm if this is the correct approach, or suggest an alternative? </div>
