<div class=Section1>
<p class=MsoNormal>I have to type this out before my brain explodes and I
forget everything….<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I'm plotting some RUC model data… <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>- When I try to create the CTL file off of a GRIB2 file
using g2ctl and display it in GrADS, GrADS gives me an error: "Unknown
Grib2 Index Version Number"<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Ok, so I convert it to Grib1 then plot it.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>- When I convert the Ruc GRIB2 to GRIB1 using cnvgrib, I
have a hunch that it's not converting the GRIB file correctly all the time
because…<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal> 1)
If I manually try to execute cnvgrib.exe through a cmd prompt (using windows) it
seems it will occasionally get an error that is resolved by rebooting the
computer. The error says it could be a problem with cygwin1.dll and it also
suggests rebooting… so I reboot and try again and it works.<o:p></o:p></p>
<p class=MsoNormal> 2)
In my automated system that uses this Grib2->Grib1 step, some data is good,
and others are really odd… it seems like its missing data or perhaps the
data isn't even packed correctly. Other runs of data are fine.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>So with all that said I guess my questions are:<o:p></o:p></p>
<p class=MsoNormal>- Why does GrADS give me the "Unknown Grib2 Index Version
Number" error if I try to load a Grib2 file, and how do I work around
that?<o:p></o:p></p>
<p class=MsoNormal>- Why would cnvgrib.exe not work without error unless I do a
reboot of the PC?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I'll also take any other ideas on how to load grib data so
it is properly read reliably.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
