<p>Hi Dennis,</p>
<p><br>
</p>
<p>Thanks for providing these files.<br>
</p>
<p>Correct me if wrong - but it appears the EASE files provided only cover the Northern Hemisphere (<span>min=0.00012 max=90</span>)?</p>
<p><br>
</p>
<p>And, therefore setting <span><i>res@gsnPolar = "SH" </i>produces missing values in the plots.</span></p>
<p><span>During the regridding several warnings also produced: <i><span>warning:avg: Entire input array contains missing values, can't compute average</span></i><br>
</span></p>
<p><span><br>
</span></p>
<p><span>If this is the issue, and since I am interested in the SH, is it possible to upload EASE grids that include the SH?</span></p>
<p><span><br>

<p><span>Thanks,</span></p>

<div>The 'EASE.nc' and 'CCSM4.nc" files are not available. However, the source CCSM4 file contained data on a rectilinear grid. We have several EASE grid files which contain the latitude and longitudes for several EASE configurations. Hence, you want rectilinear
to curvilinear regridding. Attached is a sample output (png) and the NCL script used. The script is similar to ESMF_regrid_9.ncl<br>
<br>
</div>
I have placed the source ERAI file and several files containing various latitude and longitude grid configurations at the following ftp location:<br>

The example uses the EASE (721,721) grid.<br>
<br>
</div>
You may wish to test the bilinear and conservative methods.<br>
</div>
Generating the weights for the conservative method may take some time.<br>

<p>Hi all,</p>
<p><br>
I am attempting to regrid ERA-Interim to an EASE grid, using for example the script
<a href="https://www.ncl.ucar.edu/Applications/Scripts/ESMF_regrid_9.ncl" target="_blank">
https://www.ncl.ucar.edu/Appli<wbr>cations/Scripts/ESMF_regrid_9.<wbr>ncl</a></p>
<p><br>
</p>
<p>The files "EASE.nc" and "CCSM4.nc" are not available on the example data page<a href="http://www.ncl.ucar.edu/Applications/Data/" target="_blank"> http://www.ncl.ucar.edu/Applic<wbr>ations/Data/
</a><br>
</p>
<p>can they please be added?</p>
<p><br>
</p>
<p>Regards,</p>
Peter</div>
