NASA is planning an Oct. 27 launch of the first Earth-observing satellite to measure both global climate changes and key weather variables. The National Polar-orbiting Operational Environmental Satellite System Preparatory Project (NPP) is the first mission designed to collect critical data to improve weather forecasts in the short-term and increase our understanding of long-term climate change. NPP continues observations of Earth from space that NASA has pioneered for more than 40 years.NPP’s five science instruments, including four new state-of-the-art sensors, will provide scientists with data to extend more than 30 key long-term datasets. These records, which range from the ozone layer and land cover to atmospheric temperatures and ice cover, are critical for global change science.
“NPP’s observations of a wide range of interconnected Earth properties and processes will give us the big picture of how our planet changes,” said Jim Gleason, NPP project scientist at NASA’s Goddard Space Flight Center in Greenbelt, Md. “That will help us improve our computer models that predict future environmental conditions. Better predictions will let us make better decisions, whether it is as simple as taking an umbrella to work today or as complex as responding to a changing climate.”
NPP serves as a bridge between NASA’s Earth Observing System of satellites and the planned Joint Polar Satellite System (JPSS), which will collect climate and weather data. JPSS will be developed by NASA for the National Oceanic and Atmospheric Administration (NOAA).
