<div dir="ltr"><div class="gmail_default" style="font-size:small">Barry,</div><div class="gmail_default" style="font-size:small"><br></div><div class="gmail_default" style="font-size:small">The ESMF_regrid function creates three NetCDF files:</div><div class="gmail_default" style="font-size:small"><ul><li>a source file (called <a href="http://source_grid_file.nc">source_grid_file.nc</a> by default)</li><li>a destination file (<a href="http://destination_grid_file.nc">destination_grid_file.nc</a>)</li><li>a weights file (<a href="http://wrfout_temp_rect.nc">wrfout_temp_rect.nc</a> in this script)<br></li></ul></div><div class="gmail_default" style="font-size:small"><br></div><div class="gmail_default" style="font-size:small">The error message is likely coming from ESMF_regrid trying to create the file for writing, and not for reading. The error message is a little odd, however, because it seems to indicate it doesn't recognize NetCDF as a file format which is unlikely. Also, why did it give you an error on the <a href="http://destination_grid_file.nc">destination_grid_file.nc</a> file, and not the <a href="http://source_grid_file.nc">source_grid_file.nc</a>, which should have been created first?</div><div class="gmail_default" style="font-size:small"><br></div><div class="gmail_default" style="font-size:small">My first guess would be that the file can't be created, maybe because you don't have write permissions in the directory where the script is being executed, or maybe the file is too large. But, the error message just doesn't quite match those scenarios.</div><div class="gmail_default" style="font-size:small"><br></div><div class="gmail_default" style="font-size:small">The other possible issue is that it is trying to create a NetCDF4 file, and perhaps you don't have an NCL that is NetCDF4-enabled, but this doesn't seem likely either.</div><div class="gmail_default" style="font-size:small"><br></div><div class="gmail_default" style="font-size:small">Do you have a "<a href="http://source_grid_file.nc">source_grid_file.nc</a>" in that directory that was created by that script?</div><div class="gmail_default"><font color="#000000" face="arial, helvetica, sans-serif"><br></font></div><div class="gmail_default"><font color="#000000" face="arial, helvetica, sans-serif">Can you tell me what version of NCL you have, so I can look up exactly what line in ESMF_regridding.ncl it is failing on?
