Instead of `eof1_unmasked=np.array(eof1)`, you could do `eof1_unmasked = eof1.data`. The '.data' attribute points to  a view of the masked array as a simple ndarray.

You may also wanna try `eof1.torecords()` that will return a structured array with dtype `[('_data',type_of_eof1),('_mask', bool)]`.
