Beth,
          I am going to add N0W, NCO, NCZ, NSW, and maybe DPA, NVW to the 
library. I can not find the definition of some of the products you mentioned 
here, such as, SUP, NPS, and IRM, and some products from the Unidata IDD stream 
not in the list either.

something in the whole radar sweep. You could make out when the line of precip 
moved through, and it was radial velocity...but not the same as NOV. Not sure 
if it is just a different level or what. Maybe storm relative...I'm not sure.
