NBM Grib2 Files
The master files contain all available elements in Grib2 format (specifications can be found on the
NBM Grib2 Specifications Page
). Files are in directories where
YYYYMMDD
is the run date-stamp, and
CC
is the cycle. File names are as follows:
blend.tCCz.core.fXXX.RR.grib2
(for most NBM elements) or
blend.tCCz.qmd.fXXX.RR.grib2
(for QMD elements), where
CC
is the cycle,
XXX
is the forecast hour, and
RR
is the region. (Example: blend.t00z.master.f001.co.grib2) There are also limited numbers of other elements available by single file. These files are available for 1-2 days.
