Yes, of course. But I thought netCDF4-extended meant NetCDF on HDF5, making use of all the HD5 features. So I didn't think that was the tradeoff here. > Also, while unsigned types are a feature of the netCDF4/HDF5, strictly speaking, the netCDF4 unsigned types are not compatible with any released version of the CF specification Sure, though if you're strictly following CF, you probably would use `valid_min`/`valid_max`/`valid_range` instead of `_Unsigned`... Anyways, again I don't really have an objection here. This attribute can be interpreted in a pretty unambiguous way, so adding support for this would be mostly harmless.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,233992696 https://github.com/pydata/xarray/issues/1444#issuecomment-306712888,https://api.github.com/repos/pydata/xarray/issues/1444,306712888,MDEyOklzc3VlQ29tbWVudDMwNjcxMjg4OA==,1217238,2017-06-07T07:34:05Z,2017-06-07T07:34:05Z,MEMBER,"To clarify: I didn't want to let NetCDF4-python parse this attribute, because it would break an invariant in our data model. I'm not opposed to supporting this separately in xarray (using xarray's machinery for handling netcdf conventions). I will say though that this convention makes little sense to me for netcdf4/hdf5 files, which already provide native support for unsigned types, so separately I would also encourage this data provider to change their practices here :).","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,233992696
