Detail: NOAA continues the recovery. SNPP Instrument heater activation activities were completed on Monday, August 8. Instrument science data activation activities commenced on Wednesday, August 10 and will continue through Thursday, August 11. The process is sequential (in the order of ATMS, VIIRS, OMPS, CERES, and CrIS). After all of the instruments are activated then the HRD transmitter will be powered on. As of this update, ATMS, VIIRS, OMPS and CERES have been activated. The HRD transmitter remains off and is currently planned to be turned on by August 12. The NOAA Cal/Val teams are focusing their analysis on observed data following this timeline. Users are advised that global products will not be available from PDA until they are checked out by the NOAA instrument and calibration and validation teams. Direct Broadcast (DB) users are advised that science data will not be of operational quality pending full product recovery.
Revision History: [Original] Investigation is ongoing. [Rev.1] Subject updated. [Rev.2] Correction: Impacted products and services have been updated. [Rev.3] As of 17:30 UTC (July 28, 2022), NOAA continues to investigate the S-NPP anomaly and prepare a plan to return the S-NPP spacecraft back to nominal status. These efforts are expected to continue into next week. S-NPP is currently in sun point (sun-safe) mode and all instruments are in a safe state. Although the HRD transmitter remains on, Direct Broadcast (DB) users are advised that science data is not available. All missed data will not be recoverable. No data is available starting at 16:09 UTC, July 26, 2022. Impacted products and services have been updated.
