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)

That's what I had mind. The loop should not be that much of an issue. Thanks for coming back and thanks for the code snippet.

It seems that for your case it would be enough to fix the `add_offset` and let xarray decode the dataset after that. ","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,731681563
