The use of pytest.config in the `xarray/tests/__init__.py` seem to have been introduced in #1336.  From the discussion in pytest-dev/pytest#1688 it seems as if the use of `pytest.config` is discouraged.","{""url"": ""https://api.github.com/repos/pydata/xarray/issues/1353/reactions"", ""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,completed,13221727,issue

Currently loading these files in xray raises a ValueError in the `decode_cf_variable function`.

Netcdf4-python returns a NumPy masked array with all values in the missing_value vector to np.ma.masked, xray may want to copy this model by replacing these elements with NaN.  Another option is to raise an more appropriate error indicating that these files are not supported as vector missing_value attributes do not seem to meet a strict reading of [section 2.5.1 of the CF conventions](http://cfconventions.org/Data/cf-conventions/cf-conventions-1.6/build/cf-conventions.html#missing-data).

I can provide an example file if desired.
