For specific functions available see the GPARM online documentation.

Since the last update, which involved testing only the ingest and decoding of CONDUIT 0.5/2.5 degree GFS, I've opened up the NGRID and NEXRAD3 feeds, as well as text and satellite products from the WMO and NIMAGE feeds, respectively.
The goal is to compare the speed of the grid decoder on high-resolution CONDUIT GFS runs alone versus running in parallel with the full nationwide NEXRAD3 feed and other products.
