<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>This is perfect -- EXCEPT -- that what I'm doing is actually
using GrADS (or maybe its OpenGrads, I'm not sure) to regrid the data into a
new netCDF file. I'm not using GrADS itself for display until after I've
combined several NetCDFs into one large NetCDF file. The point of this is so
that I can properly overlay data at the same points (radar data..overlaying
overlapping radar sites).<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>… so right now I'm looking at the data and choosing which
value to use at a specific coordinate given multiple radar sites, but I don't
know that I can identify what the coordinate is of the data point I'm looking
at using re(). Maybe I'm just not using it properly.<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>What I want to do is know the actual coordinate so I can
identify how far away it is from the radar site, and then with that information
decide if I want to identify the return for that point as ground clutter and
set its value to 0.<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";

<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>So in short…. I need something like defval, but I need to
be able to do it during the regridding process, not involving the display in
GrADS. I want to do it before I write out the final NetCDF.<o:p></o:p></span></p>
