Michael Anderson commented on CLIMATE-797:
------------------------------------------

run_RCMES.py sets ref_dataset and model_datasets with calls to spacial_regrid 
which returns an OCW dataset.

run_RCMES.py then apply a mask to the dataset.

An OCW dataset has a values member variable.  values: Three dimensional numpy 
array of parameter values with shape [timesLength, latsLength, lonsLength].

Mask is a member variable of a numpy masked array and values is just a numpy 
array.

The line producing the error is dataset.values.mask == True applied to the OCW 
dataset, but rightfully so as the calling program is not passing in an object 
of the expected type.  I.e. values in the dataset is not a masked array.
