hi Eduardo
I'm not sure about the grib file, but for the .nc file, I would try using 'xdfopen' where you create a .ctl to override the dimensions. see:
http://cola.gmu.edu/grads/gadoc/gradcomdxdfopen.html
also, if you send the .grib or .nc I'll take a look
Best Regards, Mike

Subject [gradsusr] issues in displaying ERA5 data
Hi everyone:
I have recently experienced problems in using ERA5 data, downloaded using either the website or the python script either in Grib or nectdf format.
When I read the files using Grads, the metadata is read, the file is open, but the vertical dimensions LEV (Z) appears as a decimal --(negative) value, with a warning message that I copy below.
Because of this, any data can be display and access.
Is there any way to solve this issue?
Thanks,.
Eduardo.
