Wgrib is a program to manipulate, inventory and decode GRIB files. The program is very portable and works on a wide variety of different computers. For NCEP users, wgrib (gributil) can now be used by operational jobs.

The current version is v1.6.0.

Hightlights for v1.6.x:

• optional binary output of PDS and GDS
• thinned grid support
• fix of my mis-interpretation on how year 2000 is stored in GRIB
• NCEP operational table
• updated documentation

Under testing:

• -d all (decode entire file)
• beta version

Note: there were two definitions for SNOC and CWAT in the operational and Reanalysis grib tables. For the time being, I'm calling snow cover "SNOWC" and canopy water "CNWAT."

To do:

• ensemble information (need information on how ECMWF encoded data)
