GRIB2 Scott Lindstrom Dave Parker [Server programmer] [JPEG 2000 installer]

GRIB2 Transmission standard for NDFD About 4 years old now Slowly replacing GRIB data in NCEP datafeeds Files designed to be general and flexible

GRIB2 Data are encoded with JPEG 2000 compression JasPer library is used for JPEG 2000 functions Compiles on all McIDAS-supported platforms [some more easily than others]

GRIB2 No more gbtbpds.* tables -- everything is defined within the GRIB2 file GRIB geographic numbers have been eliminated But this is how all RTGRIDS/RTGRIBS datasets are differentiated How to distinguish between datasets?

GRIB2 GRIB 2 files are all self-contained A server must anticipate a multitude of possibilities -- testing scripts will be very complex

GRIB2 Testing in SSEC Data Center slotted for first quarter of 2006
