NOAA sets 10:40 a.m. EST cutoff for Suomi NPP data on November 2
Update #3 sets the final cutoff at 15:40 UTC on November 2; an earlier notice carried a different time. All remaining S-NPP science products and high-rate direct broadcast are affected; this is a permanent cessation. NOAA identifies NOAA-21 as the primary replacement and NOAA-20 as secondary. Deorbit operations are planned for December.
U.S. users of Suomi NPP satellite products need to prepare for a permanent data cutoff on November 2 at 15:40 UTC, or 10:40 a.m. Eastern Standard Time. NOAA’s latest notice replaces the earlier 13:00 UTC time and directs users toward NOAA-21 and NOAA-20 products.

The October 30 update lists remaining products from ATMS, CERES, OMPS and VIIRS among the affected data streams. CrIS operational use had already ended on December 23, 2025, so that earlier change is separate from the November cutoff.
For U.S. organizations that ingest polar-orbiting observations, the practical task is to check which workflows still depend on S-NPP. NOAA’s replacement guidance points to comparable observations from NOAA-21 and NOAA-20; it does not mean that an existing S-NPP feed will continue under the same name.
NOAA says the satellite is to be lowered incrementally beginning December 1, with the process extending through approximately December 12 for reentry over the South Pacific. Those are planned operations, not a report that reentry has already occurred.
The immediate deadline concerns data delivery. Users should distinguish the final time in Update #3 from the older reminder still reproduced farther down the same notice, and check NOAA’s operational updates as the transition proceeds.
