The VIIRS Level 1 and Level 2 swath products are generated from the processing of 6 minutes of VIIRS data acquired during the S-NPP satellite overpass. The VIIRS sensor has 16 moderate-resolution channels (M-bands) that have 16 detectors (16 rows of pixels per scan), that span the wavelengths from 0.412 µm to 12.1 µm. The VNP02MOD product is comprised of 16 bands that are sensitive to visible, near-infrared (NIR), and thermal wavelengths.

The spatial resolution of the instrument at viewing nadir is approximately 750 m for the Moderate-resolution and Day/Night Bands, and 375m for the Imagery bands.
