SUBJECT: ADMINISTRATIVE: UPDATE #3 - CRIS ON SNPP SWITCH TO SIDE 1
--000000000000526E7905C79373B5
CONTENT-TYPE: TEXT/PLAIN; CHARSET="UTF-8"

UPDATE #3: THE SNPP CRIS SIDE SWITCH ACTIVITIES HAVE BEEN SUCCESSFULLY
COMPLETED AND THE SIDE-1 LWIR AND SWIR BANDS ARE FUNCTIONAL, WHILE
THE MWIR
BAND IS NON-OPERATIONAL. THE SNPP CRIS SDR PRODUCTS WILL BE DECLARED
PROVISIONAL ON WEDNESDAY JULY 21, 2021 FOLLOWING THE SDR SCIENCE REVIEW
TEAM APPROVAL. EDRS WILL BE AVAILABLE ONCE VALIDATED BY THE SCIENCE
TEAM.

UPDATE #2:  DAY 2 ACTIVITIES HAVE BEEN COMPLETED AS PLANNED.  REMAINING
ACTIVITIES ARE ON SCHEDULE TO BE COMPLETED ON JULY 14TH.

UPDATE #1: DAY 1 COMMANDING ACTIVITIES HAVE BEEN COMPLETED AS PLANNED.
THE
REMAINING ACTIVITIES ARE ON SCHEDULE TO BE CONDUCTED ON JULY 13-14,
2021 AS
OUTLINED IN THE ORIGINAL NOTIFICATION.

TOPIC: CRIS ON SNPP SWITCH TO SIDE 1 ON JULY 12 2021

DATE/TIME ISSUED: JULY 20, 2021 1955 UTC

PRODUCT(S) OR DATA IMPACTED:  ALL NPP CRIS PRODUCTS

DATE/TIME OF INITIAL IMPACT:  JULY 12, 2021 1107 UTC

DATE/TIME OF EXPECTED END: JULY 14, 2021 AT 1749 UTC (PLANNED)

LENGTH OF OUTAGE: ~54 HOURS (PLANNED)

DETAILS/SPECIFICS OF CHANGE:

CRIS ON SNPP HAD AN ANOMALY ON MAY 21, 2021 WHICH RESULTED IN THE
LOSS OF
LONGWAVE INFRARED IR) (LW) CHANNELS - ONLY THE SHORTWAVE (SW)
AND MIDWAVE
(MW) CRIS IR SPECTRUM PORTION HAS BEEN AVAILABLE SINCE THE ANOMALY
OCCURRED.  A SWITCH TO THE SIDE-1 ELECTRONICS IS SCHEDULED TO OCCUR
STARTING ON JULY 12, 2021, SINCE NUMERICAL WEATHER PREDICTION (NWP)
CENTERS
AND THE NUCAPS/HEAP EDR PROCESSING UTILIZE MORE OF THE CRIS LW IR
SPECTRUM. THERE IS A HIGH PROBABILITY THAT BOTH THE SWIR AND THE
LWIR BANDS
ARE FUNCTIONAL AFTER SWITCHING TO SIDE-1 ELECTRONICS; HOWEVER, THE MWIR
BAND WILL NOT BE AVAILABLE, AS IT FAILED BACK IN 2019.

OSPO SATELLITE ENGINEERING AND OPERATIONS WILL SWITCH THE S-NPP
CRIS SENSOR
TO THE SIDE-1 ELECTRONICS BEGINNING ON JULY 12, 2021 AT 1107 UTC AND
COMPLETING ON JULY 14, 2021 AT 1749 UTC.   DURING THAT PROCESS, NO CRIS
DATA FROM SNPP WILL BE AVAILABLE.  AFTER THE SENSOR SIDE SWITCH IS
COMPLETED, CALIBRATION/VALIDATION EFFORTS WILL BE INITIATED BY THE
NESDIS/STAR CRIS SDR ALGORITHM CALIBRATION/VALIDATION SCIENCE TEAM TO
ENSURE THE SNPP CRIS CALIBRATED DATA IS AT THE HIGHEST QUALITY
AND MEETS
THE JPSS MATURITY LEVELS.

AFTER THE SIDE SWITCH OCCURS, SNPP CRIS DATA WILL ONLY BE AVAILABLE
FROM
CLASS AND GRAVITE. THESE DATA WILL BE SUSPENDED FROM NDE/PDA UNTIL
CLEARED
BY THE CALIBRATION/VALIDATION SCIENCE TEAM.
