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.
VIIRS features daily multi-band imaging capabilities to support the acquisition of high-resolution atmospheric imagery and other instrument products, including visible and infrared imaging of hurricanes and detection of fires, smoke and atmospheric aerosols.
VIIRS extends and improves upon a series of measurements initiated by the Advanced Very High Resolution Radiometer (AVHRR), the Moderate Resolution Imaging Spectroradiometer (MODIS) and the Operational Linescan System (OLS). VIIRS has better spatial resolution with a larger swath as compared to legacy imagers. In fact, it was the VIIRS' Day/Night Band sensor that captured the widely popular and beautiful Earth at Night" Black Marble image [PDF].
