The Near Real Time (NRT) VIIRS Level 1 and Level 2 swath products are generated from the processing of 6 minutes of VIIRS data acquired during the JPSS1 satellite overpass. The VIIRS sensor has 5 high-resolution imagery channels (I-bands) that have 32 detectors (32 rows of pixels per scan), with twice the resolution of the M-bands and the DNB, that span the wavelengths from 0.640 micrometer to 11.45 micrometer. The VIIRS/NPP Imagery Resolution 6-Min L1B Swath 375m NRT (VJ102IMG_NRT) product is comprised of 5 bands that are sensitive to visible, near-infrared (NIR), and thermal wavelengths.
The spatial resolution of the instrument at viewing nadir is approximately 375 m for the Imagery bands, and 750m for the DNB and the Moderate-resolution Bands.
