Reduced quality NOAA STAR S-NPP SST data during inclination adjustment maneuver

NOAA STAR has announced that four granules of S-NPP SST data contain defective results during the satellite inclination adjustment maneuver. The affected data are within the observation time coverage of 2019-09-26T16:10:00 and 2019-09-26T16:50:00, during which the sensor was pointing to the wrong direction. Unfortunately the reduced quality data was not flagged in the L1b data and resulted in SST anomalies (much too warm SST retrievals). Mostly, the affected area is around Japan/Australia region. Both PO.DAAC and STAR have decided to quarantine the affected granules to a retired location, which includes:
