Joint Polar Satellite System (JPSS)
Real-time weather and climate data for essential forecasts. That’s Defining Possible.
Northrop Grumman is NASA’s partner to build the JPSS-2 (now NOAA-21), -3 and -4 satellites and the Advanced Technology Microwave Sounder (ATMS) instrument.
About JPSS
JPSS is a series of polar-orbiting environmental satellites. Jointly managed by NASA and NOAA, it is considered a pillar of the global Earth observing system. The satellites cross the equator 14 times a day and have advanced capabilities to measure temperature, moisture, clouds, rainfall, dense fog, volcanic ash, fire locations, smoke plumes, vegetation, snow and ice cover, and ozone. This data is critical for scientists and researchers to make weather forecasts and monitor climate change to make urgent decisions on emergency preparedness for events like hurricanes and long-term assessments for threats like droughts.
