Jeff,
Below is a sample of code which generates US 1km reflectivity using GDPLOT3.
This is probably a complicated way of getting an image, but it works.
1) copy $GEMTBL/colors/coltbl.xwp to your working directory (i.e. the
directory you are running GDPLOT3 in)
- GEMPAK looks for this table by default in the current working
directory before $GEMTBL/colors/coltbl.xwp
2) update the colors in coltbl.xwp to match unisysn0r.tbl or customize to
your liking
3) notes about code below...
- sge(n0r,15) removes radar echoes below 15dbZ (mostly ground
clutter)
- There is one more FLINE than FINT. Each FLINE refers to the 3rd,
4th, 5th color in coltbl.xwp

Subject: [gembud] FNEXRAD Help .. sooooo close
Ok I'm at wits end ..
I have been hammering my head most of the weekend trying to use
the FNEXRAD 1km GRIB file
the data is getting to where its suppose to be
problem is .. about 7 out of 10 times I run the following script
I get an image, its not correct, but at least I get something ..
the image I get is numbers plotted around each radar locale
The error below I always see .. with or with out an image
