The known GRIB2 bugs are listed below. The SSEC inquiry system number

- GRIB1 global stitched grids are not working properly. [Inquiry
13848]
- Local GRIB2 files do not work on 64 bit Linux machines. [Inquiry
13838]
- Create a slightly new dataset naming convention, because of all
of the new types of data that could be coming in GRIB2 format. [Inquiry
13832]
- GRDLIST FORM=ALL should be updated, so that GRIB2 files list the
Geographic and Parameter IDs as N/A or X. With
this change, then the GRIB IDs would still be listed in the order
that the GRIB= keyword requires. [Inquiry
13833]
- Dateline problems with some ABOM GRID files. [Inquiry
13154]
- Local GRIB datasets do not handle position numbers correctly.
[Inquiry

not have room to display all four characters. [Inquiry
13834]
- GRDDISP RTGRIB2/GFS-PRME plots a map over Puerto Rico, but no
data plots. [Inquiry
13835]
- Some datasets have missing values of 9999 instead
of x80808080 (e.g., GFS-USLCAWI4, NDF-USLCAWI4,
LMP-USLCAWI4). [Inquiry
13836]
- The RTMA GRIB2 files appear to be 1-second grids instead of 1-hour
grids. [Inquiry
13837]
Additional notes:
- We've had many problems with the units being sent in the GRIB2
files are not what are advertised by NCEP/WMO. If you see any
units problems, please
let us know.
- We still need to do a full system test of GRIB1 data with the
updated GRIB server.
- Additional testing of Ensemble datasets [Inquiry
13284] is needed.
