<br><br></div></div></div></div></div></div></blockquote><div><br>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:<br>
<br>ssh_data = ssh[:]<br><br>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.<br><br>I hope that helps!<br>Ben Root<br><br></div></div>
