This lesson introduces the VIIRS imager that operates on the current U.S. Suomi NPP satellite and is planned for future JPSS environmental satellites. VIIRS has many advanced features that improve both spectral and spatial resolution and enable the delivery of consistent, high quality, and high resolution data to users worldwide. The lesson covers the enhanced capabilities of VIIRS and highlights some of its applications. These include single channel and multispectral products used to monitor dust, volcanic ash, convection, fog and low clouds, sea surface temperature, tropical cyclones, contrails, and ocean color. A special feature on VIIRS, the Day Night Band low-light visible channel, is also introduced. For more information on the channel and its capabilities, users are referred to the COMET lesson "Advances in Space-Based Nighttime Visible Observation."
