NASA: NPP Polar Orbiting Environmental /Weather Satellite


The launch of a new polar-orbiting environmental satellite enables NOAA to continue issuing accurate
forecasts and provide advance warning for severe weather, such as deadly tornado outbreaks, blistering
heat waves, floods, snowfall and wildfires.

The satellite, NASA’s NPOESS Preparatory Project (NPP), orbits Earth every 102 minutes, flying 512 miles above the surface, and capturing data from the Earth’s land, oceans, and atmosphere.

The data is used by NOAA forecasters to detect the potential for dangerous weather conditions days – even several weeks, in advance.

For example, data from polar-orbiting satellites helped NOAA meteorologists predict, 5 days in
advance, the major snowstorms that struck the Atlantic Coast in February 2010 (“Snowmageddon”) and
paralysed New York City in December 2010.
