Visible Infrared Imaging Radiometer Suite


The sensor is a component of the Suomi National Polar-orbiting Partnership (NPP) satellite. The Joint Polar Satellite System (JPSS), a NOAA/NASA program, and the Defense Weather Satellite System, a U.S. Air Force program, were tasked with the next generation requirements for environmental research, weather forecasting and climate monitoring measurement capabilities

VIIRS, a scanning radiometer, collects visible and infrared imagery and radiometric measurements of the land, atmosphere, cryosphere, and oceans. VIIRS data is used to measure cloud and aerosol properties, ocean color, sea and land surface temperature, ice motion and temperature, fires, and Earth’s albedo. Climatologists use VIIRS data to improve our understanding of global climate change.
