These products are grids. So all GFUNC operations can be used with the data. Here is an example of the gdplot2 script creating the images at: http://motherlode.ucar.edu/unidata/images/nids/gdradr.html The reflectivity field is N0R, so that is the GDPFUN in the script below. I set up the NEXR and NEXF templates in the $GEMTBL/config/datatype.tbl file so that the location and file names are defined. Then, you only need to specify GDFILE as nexr or nexf and GDATTIM=last to get the most recent grid. The rest is pretty self explanatory if you have written any scripts to plot model grids etc. Let me know if you have questions.
