ERROR: The mandatory field TT was not found in any input data (version 4.5)


New member

I was following the Tutorial Compiling WRF.
geogrid.exe and ungrib.exe works fine but metgrid.exe fail with Error:

I tried this on WPS latest masted and release-v4.5 which is one of the solution for the same issue.

Appreciate any help!

If a mandatory field is missing, it is often because the data is not ungribbed or not available in the input data.

What is the large scale forcing data you ungrib? Where did you download this data?
I was able to fix this by downloading the fresh dataset and making sure to update the correct parameter in namelist.input file.
