Joint Polar Satellite System-1  

The next polar-orbiting weather sat 

The Joint Polar Satellite System (JPSS-1), now known as NOAA-20, will collect critical data for civil and military weather-forecasting, storm tracking and climate-monitoring, above and beyond what’s available today. 

Data and imagery from JPSS will save lives and protect property by increasing the timeliness and accuracy of weather event warnings and forecasts.  The National Weather Service will feed JPSS data into models used for long-term weather forecasting, allowing scientists and forecasters to monitor and predict weather patterns with greater speed and accuracy. JPSS is also key for the continuity of long-term climate measurements, following the Suomi National Polar-orbiting Partnership spacecraft now on orbit, which we also built and integrated. 

JPSS-1 Successfully Launched Nov. 18! Click here for a hi-res image of launch.

JPSS will fly a suite of advanced remote sensing instruments:

• The Visible/Infrared Imager Radiometer Suite (VIIRS) 
• The Cross-track Infrared Sounder (CrIS) 
• The Advanced Technology Microwave Sounder (ATMS) 
• The Ozone Mapping and Profiler Suite (OMPS)- Nadir 
• The Clouds and the Earth Radiant Energy System (CERES) 

The National Oceanic and Atmospheric Administration (NOAA) manages JPSS satellites and instruments. NASA is the JPSS acquisition lead.
