Donwscale CESM-DPLE simulations using WRF


New member
Dear forum

I am planning to downscale CESM-DPLE simulations using WRF. Based on this post I am not sure if all the variables needed are available (WPS ECMWF (ds626.0) surface and isobaric levels as initial and boundary conditions) and the files I have from CESM-DPLE are in NetCDF format. The variables are skin temperature, sea level pressure, SST, surface pressure, specific humidity, temperature, and u and v component of wind, 2m temperature, soil temperature (in top 10 cm of soil and vegetated land units), 10 m u and v and volumetric soil level, surface Geopotential and Geopotential height at 300 and 500 mb.

I would like to know if i)I can run WRF with only these variables. I only have volumetric soil water and not soil moisture and Geopotential height only available at surface 300 and 500 mb and ii)someone can help me convert these files to intermediate WPS format.



Required Meteorological Fields for Running WRF are listed below:​
