May 25 at ~22:30 UTC, the GPS on the S-NPP spacecraft experienced errors and the geolocation of all observed data became inaccurate and out of the mission specifications. S-NPP VIIRS geolocation errors caused significant data quality degradation. As of May 30, 2024, S-NPP VIIRS ACSPO SST operational products are no longer being used. The N21 VIIRS ACPSO SSTs will replace the S-NPP VIIRS ACSPO SSTs in the gap-free BSST products starting in June 2024.
