Subject: Updated:  Operational transition of the GOES-19
satellite to become GOES-East on or after April 7, 2025

Updated to reflect the operational transition is delayed from
April 4, 2025, due to critical weather day.

On or after April 7, 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

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-
