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.


Sensor SummaryThe Medium Resolution Imaging Spectrometer (MERIS) is a programmable, medium-spectral resolution, imaging spectrometer operating in the solar reflective spectral range. Fifteen spectral bands can be selected by ground command. The instrument scans the Earth's surface by the so called "push-broom" method. Linear CCD arrays provide spatial sampling in the across-track direction, while the satellite's motion provides scanning in the along-track direction.
MERIS is designed so that it can acquire data over the Earth whenever illumination conditions are suitable. The instrument's 68.5° field of view around nadir covers a swath width of 1150 km. This wide field of view is shared between five identical optical modules arranged in a fan shape configuration.
Data Record PeriodOur set of data records covers the entire routine operations period from 2002-04-29 to 2012-04-08.
