CORRECTION TO UPDATE #11: February 20, 2024: Reset of VIIRS command processor which will result in an eight to ten hour loss of data between approximately 14:00 UTC - 22:00 UTC.


February 21, 2024 or February 22, 2024: Reboot of CrIS which will result in an eight to ten hour loss of data on that date between approximately 14:00 UTC - 22:00 UTC.


Update  #12: All NOAA-20 OMPS Nadir Profiler (NP) SDRs and EDRs (V8Pro) products are approved for operational use and the NDE/PDA subscriptions for these products will be enabled at 21:00 UTC, February 15, 2024. Direct Broadcast (DB) users can use the equivalent OMPS NP Community Satellite Processing Package (CSPP) LEO products for operations.


Update #11: Analysis by the Engineering and Calibration/Validation Science teams shows issues with telemetry data being received from the NOAA-20 VIIRS and CrIS instruments. The instrument vendors are recommending rebooting the CrIS instrument and restarting the VIIRS command processor. Each activity will result in data losses of approximately eight to ten hours. 


February 20, 2024: Reset of VIIRS command processor which will result in an eight to ten hour loss of data between approximately 14:00 UTC - 22:00 UTC.

February 21, 2024 or February 22, 2024: Reboot of CrIS which will result in an eight to ten hour loss of data on that date between approximately 14:00 UTC - 22:00 UTC.

Update  #10: All NOAA-20 VIIRS and CrIS SDR/EDR products were enabled at 16:30 UTC, February 9, 2024. Full assessment is still underway for some VIIRS and CrIS EDR products. Should there be any issue identified, users will be notified.

Update  #9: All NOAA-20 VIIRS and CrIS SDR and BUFR products are approved for operational use and the NDE/PDA subscriptions for these products will be enabled at 16:30 UTC, February 9, 2024. 
Direct Broadcast (DB) users can use the equivalent CrIS and VIIRS Community Satellite Processing Package (CSPP) LEO products for operations.

Update #8: The distribution of NOAA-20 CrIS and VIIRS products will be delayed until February 09, 2024 as they will need further coordination and review before their release.

Update #7: All NOAA-20 OMPS Nadir Mapper (NM) SDRs and EDRs (V8TOz & V8TOS) products are approved for operational use and the NDE/PDA subscriptions for these products will be enabled at 19:30 UTC, February 8, 2024. Direct Broadcast (DB) users can use the equivalent OMPS NM Community Satellite Processing Package (CSPP) LEO products for operations.

OMPS Nadir Profiler (NP) SDRs and EDRs (V8Pro) will be enabled once additional OMPS SDR Look Up Tables (LUTs) are ingested into operations next week.

Update #6: The distribution of NOAA-20 CrIS products will be delayed until February 08, 2024 as it needs further coordination before its release.

Update #5: VIIRS Cal/Val team is reporting a significant issue: longwave channels (M14-M16, I5), data quality flags at pixel level (QF1) are erroneous (labeled as poor qualify for good data).  As a result, the VIIRS SDR team recommends that the data should not be released until this issue is resolved.

NOAA-20 CERES products have been validated for operational use by NASA LARC Cal/Val team as of February 06, 2024 at 22:00:00 UTC. Direct Broadcast (DB) users can use the equivalent CERES Community Satellite Processing Package (CSPP) LEO products for operations.

CrIS products are still under evaluation by the Cal/Val team and are expected to be released Wednesday, February 07, 2024.

OMPS products are still under evaluation by the Cal/Val team and are expected to be approved on the afternoon of Thursday, February 08, 2024.

Update #4: NOAA-20 ATMS products have been validated for operational use by the NOAA Cal/Val team. IDPS subscriptions and deliveries of NOAA-20 ATMS products to the operational NDE and NCCF environments have been enabled for February 05, 2024 21:00:00 UTC, and products are available for distribution to PDA users.

Subscription activation of other instructions will occur throughout the week as the NOAA Cal/Val team continues their evaluation. The tentative activation schedule is as follows:

VIIRS: Tuesday, February 06 (afternoon Eastern)

CrIS: Wednesday, February 07 (sometime after 15:00 Eastern)

OMPS: Thursday, 08 (afternoon Eastern)

Update #3: Engineering returned NOAA-20 to Mission Point Mode at 4:12:52 UTC on February 4, 2024, JDAY 035, REV 32189. ATMS was placed in operational mode at 12:32:22 UTC. CERES was placed in operational mode at 12:33:52 UTC. OMPS was placed in operational mode at 14:14:15 UTC. VIIRS was placed in operational mode at 15:57:19 UTC. CrIS was placed in operational mode at 19:30:45 UTC.

PDA OPS subscriptions for all NOAA-20 science products have been disabled as of 21:18:00 UTC on February 3, 2024. NOAA-20 science product subscriptions will be activated after each product is cleared for operations by Cal/Val Team.

NOAA-20 science data is now available through GRAVITE, CLASS and NDE I&T for the Cal/Val teams to perform a full analysis. NOAA-20 PDA OPS science product subscriptions will be activated after each product is cleared for operations.

While NOAA-20 High Rate data (HRD) is enabled, Direct broadcast (DB) users are advised that this NOAA-20 science data is not yet cleared for operational use.

Update #2:  OSPO/MOD/Engineering has determined that the anomaly is the second reset of the NOAA-20 Spacecraft Command Processor (SCP). All instruments are in safe mode. Spacecraft recovery actions are underway. Stored Mission Data (SMD) and any associated products are unrecoverable. Data and advanced products will resume when the spacecraft is fully recovered.

Update #1: IDPS is not receiving any J01 SMD data until further notice. Engineering is investigating a J01 satellite anomaly. Missed data will not be recoverable.
