Subject:    Change to NEXRAD Product Dissemination via NOAAPORT/SBN
            on or Around February 2, 2022

On or around February 2, 2022, the National Weather Service (NWS)
will
change the public dissemination of NEXRAD radar products via the
NOAAPORT
Satellite Broadcast Network (SBN). Table 1 contains the WSR-88D
products
and WMO Headings the NWS will remove from the NOAAPORT/SBN service by
changing the II portion of the WMO Heading to “6i”. For example,
the
heading for NET Echo Tops 4km X 4km 41/ET will be changed from SDUS7i
to
SDUS6i. The NET Echo Tops and RSL Archive Status products are also
disseminated from the TDWR Supplemental Product Generator (SPG). The
header change to “6i” will also remove dissemination of those SPG
products
from NOAAPORT/SBN. PNS 21-55 was issued in August 2021 to solicit
comments
on this change.

Additionally, Table 2 shows WSR-88D radar products and WMO headings
that
the NWS will add to the NOAAPORT/SBN service as replacements for the
lower
resolution versions being removed.

The WMO headings for the higher resolution (super-res) products will
use
new NNN product identifiers, with the II portion remaining the same
as was
used with the lower resolution products. Sample products are
available at
https://www.roc.noaa.gov/Sample_Products/Super_Res.

Dissemination will begin from the first site, on or around February
2,
2022. If no issues or impacts are observed or reported after one
week,
additional sites will be added. Fleet-wide implementation could be
completed by February 22, 2022.

To avoid impacting Radar Product Central Collection Dissemination
Service
(RPCCDS) users, the current RPCCDS product suite will not be altered
by
this change. RPCCDS Radar Level-III products are available via TGFTP,
and
from the National Centers for Environmental Information (NCEI)
archives.
