Update #2: The required code changes to address these quality flags have been delivered to IDPS as part of the Mx2.3.7 maintenance release and are operational as of today, Jul 18 at 14:15 UTC. This will be the final update to this notice.
Topic: NOAA-20 CrIS Scan Baffle Temperature Anomaly
Date/Time Issued: July 18, 2022 1411 UTC
Product or Data Impacted: NOAA-20 CrIS Sensor Data Records (SDR) and Outgoing Longwave Radiation (OLR)
Date/Time of Initial Impact: Feb 15, 2022 2010 UTC
Date/Time of Expected End: TBD
Length of the Outage/Event: TBD
Details/Specifics of Change:
The NOAA-20 CrIS sensor is experiencing an anomaly that flags the valid data as degraded data due to the failure of a temperature sensor. The issue is caused by an intermittent electrical failure. Due to this anomaly, the Quality Flags (QFs) included in the SDR BUFR data and OLR quality flags should be ignored. Troubleshooting of the problem has been initiated. A short-term solution proposed by the SDR Science Team to fix this problem is to update the engineering packet to open the limits and prevent the flag from being set. Users will be notified when this fix will be implemented via ESPC operation.
