the problem is here,
data=np.empty([10,90,720])
you should always use np.ma.empty if you want to construct a masked empty
array.

Dear all numpy users,
I have 10 90X720 arrays. let's say they are in a list 'a' with each element
a 90X720 numpy masked array.
then I create a new empty ndarray: data
data=np.empty([10,90,720])
##first I store all the 10 ndarray in a 10X90X720 array:
for i,d in enumerate(a):
data[i]=a
dat
