VIIRS/NPP Day/Night Band 6-Min L1B Swath 750m

Metadata Updated: August 9, 2018

VIIRS/NPP Day/Night Band 6-Min L1B Swath 750m (VNP02DNB).

The Visible Infrared Imaging Radiometer Suite (VIIRS) Level 1 and Level 2 swath products are generated from the processing of 6 minutes of VIIRS data acquired during the Suomi National Polar-orbiting Partnership (SUOMI-NPP) satellite overpass. The Day/Night band (DNB) is a panchromatic channel covering the wavelengths from 500 nm to 900 nm, and sensitive to visible and near-infrared from daylight down to the low-level radiation observed at night.

The VIIRS DNB is much improved from previous products due in large part to its complicated continuous on-board calibration. In addition, new-moon Earth observations are used to estimate and remove stray light. These corrections are a first of its kind to provide on-orbit radiometric calibration. The corrections made to the DNB data are provided by the NASA VIIRS Characterization Support Team and are likely to continue to evolve given this new methodology.

The spatial resolution of the instrument at viewing nadir is approximately 750 m for the DNB and the Moderate-resolution Bands and and 375m for the Imagery bands. The DNB is aggregated to maintain nearly constant horizontal spatial resolution across the swath.

As the DNB is sensitive to nighttime radiation over the full lunar cycle, the incoming solar and lunar radiation must be properly modeled to calculate the reflectance. However, the DNB is sensitive to more sources of radiation than just the sun and moon.
