<div dir="ltr">Hi again,<br><div dir="ltr"><div><div><div><div><br></div>I've continued to investigate the issue and decided to try out using the ESMF regridding package instead. I wrote a script that does a simple interpolation using the same data and grids but using the ESMF regridding/interpolation and ran into the same issue with missing values. This script is attached below and requires the same "geo_em" file in my prior email as well as the data file. I plotted the missing values and they are in the same location. <br><br></div>To me, this indicates some issue with how I'm creating the geo_em file but I am having a hard time finding out why that might be. I'm going to continue to work on this and try a different grid to see if I run into the same issue. If anyone has any ideas I would greatly appreciate it. <br><br></div>Thanks,<br></div>Michael<br><div><div><div><div><div><div><div class="gmail_extra"><br><div class="gmail_quote">On Mon, Jun 8, 2015 at 2:26 PM, Michael Stone <span dir="ltr"><<a href="mailto:mrstone.colorado@gmail.com" target="_blank">mrstone.colorado@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div><div><div>Hi All,<br><br></div>I'm having issues interpolating data using the rgrid2rcm function from NCEP to WRF coordinates.

The NCEP data is just air temperature (although I'm trying to do many variables) and I put a single year on the NCAR ftp server under "<a href="http://air.1950.nc" target="_blank">air.1950.nc</a>". There is also a file "<a href="http://geo_em.d01.nc" target="_blank">geo_em.d01.nc</a>" that represents the WRF grid to interpolate to that is necessary for the script to run located on the ftp. <br><br></div><div>ncl -V<br><br>6.2.0<br><br></div><div>uname -a <br><br>Linux <a href="http://vardar.colorado.edu" target="_blank">vardar.colorado.edu</a> 2.6.32-504.12.2.el6.i686 #1 SMP Sun Feb 1 12:14:25 EST 2015 i686 i686 i386 GNU/Linux<br></div><div><br></div>Thanks for the help.<span class="HOEnZb"><font color="#888888"><br><br></font></span></div><span class="HOEnZb"><font color="#888888">Michael<br></font></span></div>
