VIIRS has a swath width of 3060 km at the satellite's average altitude of 829 km. This swath width is able to provide complete coverage of Earth across the day. The VIIRS instrument can collect data in 22 different spectral bands of the electromagnetic spectrum, in the wavelengths between

sensors by collecting radiometric measurements of Earth in the visible and infrared spectra. This data is used to provide insight into the properties and dynamics of different geophysical phenomena, including: aerosol and cloud properties, sea, land and ice surface temperatures, ice motion, fires,
126:
and the albedo of Earth. VIIR's main objectives include the monitoring and investigation of changes and properties in vegetation, land cover/use, the hydrologic cycle, and the earth's energy budget over both global and regional scales. This information is useful in furthering our understanding of

VIIRS is capable of generating two data processing streams that result in two different sets of land products, with global coverage every 14 hours. One is produced by
453:, 375 meters (m) and 750 m, which are resampled to three nominal spatial resolutions 500 m, 1,000 m, and 5,600 m (0.05 degrees) in the NASA produced data products.
