The implementation for this has been postponed again to August 19, due to the
hurricane.

Hi Daryl & fellow LDMers,
That SCN most certainly raised my eyebrows when it came in. As you clearly do,
I've got some questions about this too.
I'm going to inquire deeper into what this means, the implications, and what
users (not to mention us at the UPC) should do to adjust if anything. I'll
share what I learn when I hear back.
May we live in interesting times,
-Mike

Howdy LDM Users/Unidata,
The SCN below looks scary and impactful to the IDD with products changing
feedtypes. Can any of the fine folks here / Unidata put my mind at ease?
thanks!

Service Change Notice 24-54 Updated

To: Subscribers:
-NOAA Weather Wire Service (NWWS)
-Emergency Managers Weather Information Network (EMWIN)

From: David Michaud
Director, NWS Office of Central Processing
Subject: Updated: Change to NOAAPort / Satellite Broadcast Network
(SBN)
Channel Alignment, Effective June 10, 2024
Updated to change the implementation date from on or about 1200
Coordinated Universal Time (UTC) June 10, 2024, to on or about 1200
Coordinated Universal Time (UTC) July 15, 2024, and to add
information on
a recommended configuration setting.
Effective June 10, 2024, the NWS recommends that all users ensure
their
requests from NOAAPort / SBN utilize the feed type of ANY rather than
specific feed types such as HDS and NGRID. The implementation date
has
been delayed to allow users time to make these changes. After this
change
patterns could be duplicated so users should cross-check and make
sure
there are no duplicates.
An example of a request to change is for CONUS MOS products.
Before:
NGRID|IDS|DDPLUS ^(FOUS[1-589].) (....) (..)(..)(..)
After:
ANY ^(FOUS[1-589].) (....) (..)(..)(..)
>From the original SCN 24-54:
The NWS has studied the existing NOAAPort/SBN/NWWS channel alignment,
bandwidth usage, prioritization, and delay times. This study
identified
that reorganizing the data on the various channels will improve the
timeliness of distributed products.
The first of three changes to the existing NOAAPort/SBN/NWWS channels
is
to migrate all grib, grib2, and bufr formatted data from the NMC
channel
to the NMC2 channel.
The following is a list of World Meteorological Organization (WMO)
Headers
that will move: (Channel: NMC | Priority: 0 | Bandwidth: 20 | Port:
1201 |
PID: 101) to (Channel: NMC2 | Priority: 5 | Bandwidth: 30 | Port:
1203 |
PID: 103):

This data is expected to move on or about 1200 Coordinated Universal
Time
(UTC) July 15, 2024. If a Critical Weather Day has been issued, this
change will be postponed until 1200 UTC on the next non-Critical
Weather
Day.
No change is expected to the data feed at the receiver. If no issues
are
experienced, the configuration will remain in place. If any issues
are
identified, the changes will be evaluated, and a new implementation
date
will be determined.
We encourage all NOAAPort/SBN/NWWS users to closely monitor this
Service
Change Notice (SCN) during the transition period for updated
information.
