Product Anomaly: NOAA-21 CrIS SDR Anomaly
Topic: NOAA-21 CrIS SDR Anomaly
Date/Time Issued: March 3, 2025 1445Z
Product(s) or Data Impacted: NOAA-21 CrIS SDR and derived products
Date/Time of Initial Impact: March 2, 2025, 1800Z
Date/Time of Expected End: TBD
Length of Outage: TBD
Details/Specifics of Change:
NOAA-21 CrIS laser wavelength directly readout from the SDR products has
been set at as the predefined filled value (670nm, 1550 nm, 2320 nm) since around 18:00 of
2025-03-02, resulting in large bias of radiance produces of all three bands
However, the laser wavelength directly calculated from the RDR
engineering packet is nominal.
The Cal/val team is investigating the root cause of the issue.
