JPSS NPP Stored Mission Data (SMD) is unavailable from 11/01/2023 - 16:30Z until further notice due to a spacecraft anomaly. SNPP experienced another CDP reset on 11/01/2023 and the Engineering team is trying to get the spacecraft into mission point and recover communications. So far, 3 out of 5 instruments are in safe mode. Efforts are underway to ascertain the telemetry from CrIS and VIIRS. The VIIRS science data is unavailable from ~14:50Z and the data production is on hold. Further updates will follow when more information is available.

Update 11/03/2023 (2023/307): Engineering team placed the S-NPP satellite in mission-point mode and all instruments were confirmed to be in a safe state on Nov 1, 2023. Instrument activation activities commenced on Nov 2, 2023 and VIIRS was placed in operational mode at 16:09Z on Nov 2, 2023. S-NPP data is undergoing further evaluation by Cal/Val science teams and the VIIRS products may be reprocessed after the ongoing assessment of instrument performance by the NASA VCST.

Update 11/06/2023 (2023/310):S-NPP instrument activation activities are on-going. All ATMS and VIIRS products are approved for operational use.
