UPP fails due to NetCDF Attribute

[fazargoshasbi]

Hello,

I am trying to convert a wrfout file to grib to use in ungrib (WPS) by UPP4.1. However, when I run the run_unipost_frames, it fails. The following message is the error I am getting.

NetCDF error: NetCDF: Attribute not found
NetCDF error in ext_ncd_get_dom_ti.code CHAR, line 83 Element SIMULATION_START_DATE
startdate= ^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@
forrtl: severe (64): input conversion error, unit -5, file Internal Formatted Read

Any Idea how to solve this issue?
Thanks,
Forood

The run_unipost_frames script is for processing a single wrfout file that has multiple forecast times. I mention this to ensure you are using the correct processing script. The script creates the UPP 'itag' namelist from the parameters you set in the script. It appears that it's either not creating the itag correctly or not reading it correctly. Can you send your itag and run_unipost_frames?

Thank you, @hertneky . The issue was as the result of the NetCDF version. I converted the file to NetCDF-3-classic, and it solved the issue.
