If you are using cu_physics options 1 or 2, then it is possible to output HTOP and HBOT for convective clouds. These are level numbers and you have to match them with the height values in post processing. These variables are not currently in the wrfout* files. To output these variables, you need to edit the Registry file (Registry/Registry.EM_COMMON), and change the lines for HTOP and HBOT to:

state real HTOP ij misc 1 - rh "HTOP" "TOP OF THE CONVECTION LEVEL" """
state real HBOT ij misc 1 - rh "HBOT" "BOTTOM OF THE CONVECTION LEVEL" """

After this you will need to recompile the code, making sure to do a 'clean -a' and reconfigure first.

Note: These do not include information from explicit precipitation, though it may not much matter.
