Geostationary Meteorological Satellite

The Himawari (ひまわり, “sunflower”) geostationary satellites, operated by the Japan Meteorological Agency (JMA), support weather forecasting, tropical cyclone tracking, and meteorology research. Most meteorological agencies in East Asia, Southeast Asia, Australia and New Zealand use the satellites for their own weather monitoring and forecasting operations.

Originally also named Geostationary Meteorological Satellites (GMS), since the launch of GMS-1 (Himawari 1) in 1977, there have been three generations, including GMS, MTSAT, and Himawari 8/9. Himawari 8 and MTSAT-2 satellites are currently available for operational use.
