Possible Variable for Three-Dimensional Latent Heat Release in MPAS

Hello everyone,
I am currently working with MPAS v8.2.0 and trying to analyze the three-dimensional structure of latent heat release associated with tropical cyclones. While checking the variable tables in the MPAS User Guide, I only found the variable "lh", which represents the "latent heat flux at the surface" and therefore only provides information at the surface layer. What I would like to examine, however, is the vertical distribution of latent heating throughout the atmosphere. I am wondering whether MPAS provides any diagnostic variables related to three-dimensional latent heat release/heating rates, either directly from the model output or through physics parameterization tendencies. If such variables exist, I would appreciate any suggestions on their names, related namelist options, or recommended methods for diagnosing 3D latent heating in MPAS outputs.
 
MPAS provides two state variables: (1) "dtheta_dt_mp", which is potential temperature tendency from microphysics, and (2) rthcuten, which is potential temperature tendency due to cumulus convection.

We can derive the latent heating rate (and heat flux) from the the above two variables. Please add these two variables to your streams.list_atmosphere and they should be included in your history files. There are no specific namelist options required for output these variables.

Please try and let me know if you have any issues.
