Incorrect Pressure with use_theta_m = 1 (Posted Aug 14, 2018)
Problem: There is a known error in the wrf.exe program, noticeable in the pressure field, related to the usage of the moist potential temperature option (use_theta_m=1). In the WRF/dyn_em/start_em.F file, near line 782, the original code ALWAYS includes the scale factor of 1+Rv/Rd*Qv for the potential temperature. In the case that the incoming potential temperature variable is already moist theta (i.e., the user has set use_theta_m=1, which is now the default), then this is a repeated scaling.
Solution: Download this modified start_em.F file. Unpack it in the WRF/dyn_em/ directory and then recompile the code. Since there is no change to the registry, it is not necessary to clean or reconfigure. Simply recompile.
