Hi Dennis

<div class=""><br class="">

</div>

<div class="">Great that you have found the source of the problem. I had thought about using linint2_wrap; but as many other modules in the CESM model seem to use ESMF I was sticking with that.</div>

<div class=""><br class="">

</div>

<div class="">Thanks, I will wait for more news.</div>

<div class="">I think there is an issue with the ESMF regridding. I do not understand it. I may have to open a JIRA ticket.</div>

<div class="">I used<b class=""> <a href="http://www.ncl.ucar.edu/Document/Functions/Contributed/linint2_Wrap.shtml" class="">

linint2_Wrap</a> </b>to create the high resolution netCDF4_Classic file. For a 21600 x 43200 grid, linint2_Wrap is VERY slow. However, The values are likely the same or very close to ESMF bilinear regridding.
