About Suomi – NPP


The Suomi National Polar-orbiting Partnership collects and distributes remotely-sensed land, ocean, and atmospheric data to the meteorological and global climate change communities as the responsibility for these measurements transitions from existing Earth-observing missions to the NPOESS. It will provide atmospheric and sea surface temperatures, humidity sounding, land and ocean biological productivity, and cloud and aerosol properties.

Understanding, monitoring and predicting the course of long-term climate change and short-term weather fluctuations remain tasks of profound
importance. Economic competitiveness, human health and welfare, and global security all depend in part on our ability to understand and adapt to
environmental changes.


Over the last dozen years, NASA has launched a series of satellites—including those known collectively as the Earth Observing System (EOS)—that provide critical insights into the dynamics of the entire Earth system including clouds, oceans, vegetation, ice and the atmosphere.
Now NASA is helping to create a new generation of satellites to extend these global environmental observations. A critical next step in this transition is the NPOESS Preparatory Project (NPP). This Earth science satellite began in a partnership between NASA, the National Oceanic and Atmospheric Administration (NOAA) and the Air Force. That partnership, the National Polar-orbiting Operational
Environmental Satellite System (NPOESS) was reorganized and part of the system became the Joint Polar Satellite System (JPSS), which NASA is developing for NOAA.

NPP is a satellite that carries five very different instruments to monitor the environment on Earth and the planet’s climate. NPP measurements will be used to map land cover and monitor changes in vegetation productivity. NPP tracks atmospheric ozone and aerosols as well as takes sea and land
surface temperatures. NPP monitors sea ice, land ice and glaciers around the world. In addition to continuing these data records, NPP is also able to monitor natural disasters such as volcanic eruptions, wildfires, droughts, floods, dust storms and hurricanes/typhoons.In all, NPP monitors the health of Earth from space—providing continuity to decades-long records and setting the stage for future Earth science missions.

NPP is in a polar  orbit—circling the Earth  from the North Pole to  the South Pole and back  about 14 times a day.
