VIIRS, a scanning radiometer, collects visible and infrared imagery and radiometric measurements of the land, atmosphere, cryosphere, and oceans. It extends and improves upon a series of measurements initiated by the Advanced Very High Resolution Radiometer (AVHRR) and the Moderate Resolution Imaging Spectroradiometer (MODIS). VIIRS data is used to measure cloud and aerosol properties, ocean color, sea and land surface temperature, ice motion and temperature, fires, and Earth&apos;s albedo. Climatologists use VIIRS data to improve our understanding of global climate change. 

Mass: Approximately 252 kilograms
Average Power: 191 W
Development Institutions: Raytheon Company
VIIRS Sensor Lead: Bruce Guenther (NOAA)
Purpose: To collect measurements of clouds, aerosols, ocean color, surface temperature, fires, and albedo.

New Value=The Visible Infrared Imaging Radiometer Suite (VIIRS) instrument collects visible and infrared imagery and global observations
of land, atmosphere, cryosphere and oceans.

Currently flying on the Suomi NPP satellite mission, VIIRS generates many critical environmental products about snow and ice 
cover, clouds, fog, aerosols, fire, smoke plumes, dust, vegetation health, phytoplankton abundance and chlorophyll. VIIRS 
will also be on the JPSS-1 and JPSS-2 satellite missions.
