The Joint Polar Satellite System (JPSS-1), now known as NOAA-20, launched in November 2017 and is collecting critical data for civil and military weather-forecasting, storm tracking and climate-monitoring.

Data and imagery from the JPSS satellites will save lives and protect property by increasing the timeliness and accuracy of weather event warnings and forecasts. The National Weather Service is feeding JPSS-1/NOAA-20 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/NOAA-20's suite of advanced remote sensing instruments include:

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

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