Hi Brad,
I am not getting the attribute reshape for the array, are you having a different version of numpy than mine?

I have
In [55]: np.__version__
Out[55]: '1.7.0'

and detail of the shape

AttributeError: reshape

Ah, you have a NetCDF variable, which in many ways purposefully looks like a NumPy array, but isn't. Just keep in mind that a NetCDF variable is merely a way to have the data available without actually reading it in until you need it. If you do:

ssh_data = ssh[:]

Then the NetCDF variable will read all the data in the file and return it as a numpy array that can be manipulated as you wish.

I hope that helps!
