Description
The file eraint_uvz.nc contains variables which do not conform to CF standard.
Below is the ncdump of the z-variable of dtype int16 but the _FillValue is NaN. According to CF conventions _FillValue should be of same type as its variable.
ncdump:
short z(month, level, latitude, longitude) ;
z:number_of_significant_digits = 5 ;
z:units = "m**2 s**-2" ;
z:scale_factor = -1.7250274674968 ;
z:long_name = "Geopotential" ;
z:add_offset = 66825.5 ;
z:_FillValue = NaN ;
z:standard_name = "geopotential" ;
