<p>Dennis,</p>
<p><br>
</p>
<p>Thanks for the references. I was able to run Example 2 and I also looked at Example 1 and compared it to my script.
</p>
<p><br>
</p>
<p>If I understand it correctly, the error I get ('bin_sum: zlat must be the same size as zlon') is related with the dimensions of lon and lat in the original data not nlat and mlon:

<p>Thanks for your quick responses.</p>
