These satellites are critical for advanced warning of severe weather including tornado outbreaks, heavy snowfall, hurricanes, heat waves, floods, & wildfires. Data from the Suomi National Polar-orbiting Partnership (Suomi NPP) satellite will continue to strengthen NOAA’s ability to predict severe weather days in advance. Suomi NPP data are also used to generate dozens of environmental data products, including measurements of clouds, vegetation, ocean color, and land and sea surface temperatures.
