Green roof soil moisture


Dear WRF community,

I have a question about soil moisture in the green roof option. I would highly appreciate it if someone could help me.

For single layer UCM (SLUCM), how can I change the initial soil moisture of green roofs?
While green roof properties for SLUCM are specified in WRF/phys/module_sf_urban.F at master · wrf-model/WRF (such as saturation soil moisture, wilting point, reference soil moisture and residual soil moisture) I found some studies mentioning that the default initial soil moisture for green roofs is 0.20 m3 m−3 for SLUCM. Therefore, I have a question about whether there is additional file, specifying the green roof properties (Soil moisture)

Thank you!

Hi, Din19,
All the parameters for green roof in UCM are hard-coded in the code "module_sf_urban.F". There is no extra file that provides such information.
