How does UPP calculate low and high cloud cover?


New member
Hello wonderful WRF-UPP help team:

Recently, I am doing some research about cloud cover, and I noticed that UPP output file contains the calculation of low-level cloud cover and high-level cloud cover, I want to know how low-level cloud cover and high-level cloud cover are defined here, I did not find relevant content in the source code, is it the same as ERA5 definition?

Thank you.
The cloud layers computed in UPP for WRF are defined by:
Low: ≥ 642 hPa
Mid: ≥ 350 hPa
High: <350 hPa
