VIIRS is one of five key instruments onboard Suomi NPP, launched on October 28, 2011.

Outlines 1. Suomi NPP-VIIRS sensor provides as many as 22 visible and infrared bands with wavelength ranging from 0.4 to 12.5 m. Sixteen bands are Moderate-resolution bands (M-bands) and one is Day/Night Band, all at a spatial resolution of 750 m. The Visible Infrared Imaging Radiometer Suite (VIIRS) is a sensor designed and manufactured by the Raytheon Company on board the Suomi National Polar-orbiting Partnership (Suomi NPP) and NOAA-20 weather satellites. OLI, to generate a fine resolution surface water map. The Cross-track Infrared Sounder (CrIS) on Suomi National Polar-orbiting Partnership Satellite (S-NPP) is a Fourier transform spectrometer and provides a total of 1305 channels in normal mode for sounding the atmosphere. However, the effective and wide CrIS is the infrared high spectral resolution atmospheric sounder on Suomi-NPP: 1305 channels between 650 cm-1 and 2550 cm-1.

Due to their fine temporal resolution and wide spatial coverage, Suomi NPP–VIIRS data have begun to show their value in surface water and la ke-water detection.

SUOMI NPP SDR Science and Validated Product Maturity Review College Park, MD; December 18-20 2013. The 375 m product complements the baseline Suomi NPP/VIIRS 750 m active fire detection and characterization data, which was originally designed to provide continuity to the existing 1 km Earth Observing System Moderate Resolution Imaging Spectroradiometer (EOS/MODIS) active fire data record.

Introduction and objectives ... spatial resolution) 7 Q Q Q Q Q Q Q Q S d VIIRS is a whiskbroom scanning radiometer that collects imagery and radiometric … high-resolution data from the Visible Infrared Imaging Radiometer Suite (VIIRS) onboard the Suomi National Polar Orbiting Partnership (S-NPP) and on future Joint Polar Satellite System (JPSS) satellites, providing spatial detail that cannot be obtained with passive microwave data.
A threshold method is CrIS/ATMS comprise the IR/MW Sounding Suite on NPP called CrIMSS. CrIS was switched to the full spectral resolution (FSR) mode Suomi NPP, which was renamed in January 2012 to honor “the father of satellite meteorology” Verner Suomi (Lewis et al. CrIS is functionally equivalent to AIRS, the high spectral resolution IR sounder on EOS Aqua and ATMS is functionally equivalent to AMSU on EOS Aqua.
