[ncl-talk] concatenating arrays in PynGL

[Mahesh Kovilakam]

I just want to append these two arrays so that the new variable will have
values from 1979 through 2018. In NCL, I just use
array_append_record(ext_525,merged_ext_525) which will produce an array
that goes from 1979 through 2018. I am not sure in python, the "np.append"
can be used.
