Three New Satellites: SUOMI NPP, JPSS & GOES-R


Suomi NPP

Suomi NPP orbits the Earth about 14 times each day and observes nearly the entire surface, continuing key data records that are critical for climate change science.

  • ATMS (Advanced Technology Microwave Sounder)
    • used to create global models of temperature and moisture profiles
  • CrIS (Cross-track Infrared Sounder)
    • monitors atmospheric pressure and moisture, and used to produce improvements in short and long-term weather forecasting
  • OMPS (Ozone Mapping and Profiler Suite)
    • measures Earth's ozone levels, particularly near the poles where ozone levels fluctuate most
  • VIIRS (Visible Infrared Imaging Radiometer Suite)
    • collects visible and infrared views of Earth's surface processes (wildfires, land changes, ice movement)
    • also used to measure atmospheric and oceanic properties (clouds, sea surface temperature)
  • CERES (Clouds and the Earth's Radiant Energy System)
    • measures reflected solar radiation, emitted terrestrial radiation, and total radiation
    • used to monitor the natural and anthropogenic (human-caused) effects on the Earth's total thermal radiation budget.
