Turning off temperature tendencies in Thompson scheme related to melting and evaporation

[tzaremba]

Hello, I am attempting to disable the temperature tendencies in the Thompson microphysics scheme due to melting and evaporation. I am running WRFV4.4.1 on Derecho. After recompiling the code and running simulations for my outer domains (8.1 km, 2.7 km, and 900 m), I observed minimal differences in the latent heating field when the temperature tendency for melting was turned off. I would like to ensure that I have correctly modified the Thompson microphysics scheme and that I am plotting the appropriate variable (h_diabatic - the latent heating term due to microphysics). My changes in the Thompson microphysics scheme are marked with a !Modify. Additionally, are there any other steps I should take to accomplish turning off the temperature tendencies due to melting and evaporation?

Here is how I recompiled on Derecho:

Uploaded my new microphysics modules with name module_mp_thompson.f to phys folder.

./clean -a

module load ncarenv/23.06
module load intel-classic/2023.0.0
module load ncarcompilers/1.0.0
module load cray-mpich/8.1.25
module load craype/2.7.20
module load netcdf/4.9.2

./configure
Option 50

./compile em_real >& compile.log &



Thanks for your help!

Have you tried the option "no_mp_heating = 1"? It turns off latent heating from microphysics. Is this what you intend to do?
