Subject: Operational transition of the GOES-19 satellite to become
GOES-East on April 4, 2025.

On or after April 4, 2025, at approximately 15:10 UTC, GOES-19, the
newest satellite in the Geostationary Operational Environmental
Satellite (GOES) series, will become the operational GOES-East
satellite, replacing GOES-16.

As of that date, all data products from GOES-19 will permanently
replace those from GOES-16 on the Satellite Broadcast Network (SBN).
This will include:

  1. Sectorized Cloud and Moisture Imagery (SCMI),
  2. Level-2 (L2) derived products, and
  3. Other products.

1. GOES-19 SCMI will, like GOES-16 SCMI, be disseminated on the "GRE"
channel of SBN using the following WMO headers for GOES-East:

 TIRS{01..16} KNES for Full Disk imagery;
 TIRE{01..16} KNES for East CONUS imagery;
 TIRP{01..10,13,15} KNES for Puerto Rico Regional Sector
imagery;
 TIS[A-Z]{01..16} KNES for Meso sector imagery.

Note: Although GOES-19 SCMI will use the same WMO headers as GOES-16
SCMI, users can still determine the satellite source via the
"satellite_id" global attribute within each file.

2. GOES-19 L2 Derived Products on the SBN, like those from GOES-16,
will use the GOES-East WMO headers and SBN channels indicated below:

* F, C, and M denote the (GOES-East) Full Disk, CONUS, and Meso
sectors, respectively.

Note: Although GOES-19 L2 products will use the same WMO headers as
those from GOES-16, users can still determine the satellite source
via
the "platform_ID" global attribute within each file.

3. GOES-19 observations will also replace GOES-16 observations in the

These data products are further detailed in the following Service
Change Notices:

 SCN20-67 (Global Mosaic of Geostationary Satellite Imagery)
 SCN20-83 (GOES-17 (now GOES-18) ASOS Satellite Cloud Product)

Unlike SCMI and L2 products, the Global Mosaics, ASOS Satellite Cloud
Products, and Global HydroEstimators do not indicate within each file
which satellite observations they derive from.

Details on the GOES-19 Transition to Operations are available from
the
GOES-R Program at https://www.goes-
r.gov/users/transitionToOperations19.html.

Technical details on all of the above data products are available on
the NOAA VLab at https://vlab.noaa.gov/web/towr-s/dataset-guides.

Critical weather or other factors may delay these changes on the SBN.
