[Datastream #NSS-109545]: GRIB-2 files

Kevin,

The NWS has installed their new super computer last week, so the 180 day 
transition 
period of grib1 to grib2 files has started. The FTP directories will be 
populated with
grib1 versions still for at least 180 days.

The NOAAPORT broadcast has added fields in GRIB2 to the NWSTG2 channel which we
provide as the NGRID data feed. There are only a few grids being briadcast
in grib2 under the HDS (the aviation weather center grids). The NWS has volume 
restrictions on NOAAPORT to anticipate the worst case scenario (eg all radars
in precip mode, with full images etc), so duplicating within the NWSTG feed for 
HDS
probably isn't possible. Rather, the new grids such as the RUC-2 13km grids 
will be
added in the NWSTG2 feed. The NWS will announce updates on time for additions 
on their 
web site. The GFS sectors you had asked about previously are all now in the 
NGRID feed.
The NWS will announce any removals of data, after which they may have other 
data to add
in its place.
