Collection 2 S-NPP Product Descriptions: VNP02IMG_NRT

Last update: January 30, 2022

Data Set Short Name:
VNP02IMG_NRT

Data Set Long Name:
VIIRS/NPP Imagery Resolution 6-Min L1B Swath 375m NRT

Platform:
Suomi National Polar-Orbiting Partnership (S-NPP)

Instrument:
VIIRS

Product Description:
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 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 µm to 11.45 µm. The VNP02IMG 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.

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.
