Topic: SNPP CrIS Switch to Side-2 Electronics
Date/Time Issued: June 5, 2019 1745 UTC
Product(s) or Data Impacted: SNPP/CrIS products, including CrIS RDR, SDR and NUCAPS L2 products
Date/Time of Initial Impact: M-BJune 18, 2019 1800 UTC
Date/Time of Expected End: M-B~14 weeks later
Length of Outage: up to 14 weeks from time of initiation
Details/Specifics of Change: M-BDuring the week of June 17-21, 2019 a switch of the SNPP/ Cross-track Infrared Sounder (CrIS) electronics from the current side-1 to the redundant side-2 will be performed.M-B This effort will be undertaken to recover from a CrIS midwave signal processor failure that occurred on side-1. Once the switch over to side-2 is initiated, all SNPP/CrIS science data (including NUCAPS L2 data) will be unavailable for up to a two week period as instrument adjustments are being performed. Once the two-week switch effort is concluded, a 12-week Calibration/Validation effort will be undertaken to ensure the CrIS data is at the highest quality and maturity levels.
All SNPP/CrIS Products will be affected:
During the first 2 weeks, all SNPP/CrIS products will be unavailable.
After the initial 2 weeks, products will only be available to Cal/Val approved users.
When the Cal/Val period is complete, all SNPP CrIS products will be made available to all approved users.
Important note: HRD/Direct Readout users should not use the data until notified that the data has reached an acceptable maturity level. M-B
