Error in atm forcing (GSWP3) - CLM5

[ekarlsso@purdue_edu]

Hello, I have successfully ported CLM to a local cluster and am trying out some out-of-the-box test cases. I'm running the case only changing a few things per the CaseStatus file. The cesm.log* reports the following error. Additional info in attached files. I'm guessing it's an issue with NaN in my atmospheric forcing files (GSWP3 forcing), but I'm wondering how I fix the problem? What forcing files include zonal wind (Sa_u)? Or is it calculated? Do I need to change NaN's to 1e+36 (which is the -FillValue and missing_value in the forcing files? It seems all input files have NaN, so is there a quick way to do it? Thanks for any insight on this issue!

The wind components (u and v) are derived from the forcing wind magnitude which comes from the GSWP3 files (specifically, WIND in the TPQWL files).
From the atm log file, it looked like the model was running fine starting in 1901 and then crashed in Feb 1905? So it seems like your forcing files wouldn't have any NaNs from 1901 up to the point at which it crashed. Do they?
There shouldn't be any NaNs in any of the GSWP3 forcing files (I don't see any in our version of the forcing files we have here on cheyenne).

Maybe your file(s) were not downloaded completely/correctly? You could try downloading them again.

Oh, yes downloading the forcing files again worked. Thank you!
