The SNPP mission has restored data collection following a spacecraft anomaly that occurred on 26 July 2022. The VIIRS calibration team is evaluating the data to determine any impacts the two-week outage may have had on data quality. This evaluation may take several weeks to complete. Until such time as this analysis is complete and any calibration adjustments can be made, users are cautioned against using these data for scientific analyses.
