That must be it!

missing_value was set to [1] in tvariable by default

• fill_value = numpy.ma.default_fill_value(1.0).astype(dtype)
  https://github.com/UV-CDAT/cdms/blob/master/Lib/tvariable.py#L286

Assert that fill_value is set depending of dtype

        if dtype is None and data is not None:
            dtype = numpy.array(data).dtype
        if fill_value is not None:
            fill_value = numpy.array(fill_value).astype(dtype)
        else:
            fill_value = numpy.ma.MaskedArray(1).astype(dtype).item()
            fill_value = numpy.ma.default_fill_value(fill_value)

@dnadeau4 the PR is closed but not merged. Re-opening until this is clarified.

This was fill value issue that I fixed. The comment I used fix closed the issue automatically.

This must be fixed and merged at this time. They are no more commented lines in test_regrid2.py
