Yes your sparse answer did help. But to apply the fix to all add_offset for the different DataArrays within the DataSet I have to loop through them. So what I am doing to 'open' a file is. ``` python ds = xr.open_dataset('XYZ.hdf.hdfeos',mask_and_scale=False, engine='pynio')

for dataarray in ds.data_vars: if hasattr(getattr(ds, dataarray),'add_offset'): fix_offset=-getattr(getattr(ds, dataarray),'add_offset')*(getattr(getattr(ds,dataarray),'scale_factor')) getattr(ds,dataarray).attrs['add_offset']=fix_offset

ds = xr.decode_cf(ds) ```
