UPP: Problem processing old GFS nemsio data.

I'm trying to convert GDAS nemsio data from May 2019, which is the old GFS before FV3.

The unipost program broke with printouts "wrong reduced grid - execution skipped".

With the same script settings, I was able to successfully process the latest GFS nemsio though.

Wondering if anyone has experiences with this and can provide suggestions.




We do not and have not in the past tested the old GFS before FV3 (or the GDAS dataset at all) for community support of the UPP. Developers also do no currently test the old dataset. Unfortunately, we don't have any suggestions on how to process that dataset with UPP.
