Hi,
I'm currently doing some tests on the influence of using theta_m. When setting "use_theta_m" = 0 for a run with dx=1km the data written in the netCDF wrfout-files are identical for T and THM. This is also the case for wrfinput-file created by real.exe when running it with "use_theta_m" = 0
Can you confirm this and is this intentionally?

cheers,
 
When use_theta_m =0, WRF is supposed to use dry theta in dynamics. In this case, THM and T are the same, and both are perturbation dry potential temperature.
