NOAA-21 satellite is now operational
RESOURCES It’s official: NOAA-21, the latest satellite in NOAA’s Joint Polar Satellite System, is operational. The satellite joins its predecessors, Suomi NPP and NOAA-20, each circling the globe 14 times a day, providing a continuous stream of data to improve the accuracy of NOAA’s 3–7 day forecasts. This includes observations for extreme weather events and monitoring climate change. The satellite launched in November 2022 as JPSS-2 was renamed NOAA-21 when it reached orbit. NOAA-21 now gives NOAA three spacecraft operating the most sophisticated technology the agency has ever flown in a polar orbit, capturing precise observations of the world’s atmosphere
