New-generation geostationary meteorological satellites “Himawari-8/9” carry state-of-the-art optical sensor “AHI (Advanced Himawari Imager)” capable of high spatial resolution, high observation frequency, and multi band observation. AHI has 16 spectral bands, and its spatial resolution is 0.5 or 1 km for visible bands, 1 km or 2 km for near-infrared bands, and 2 km for infrared bands. AHI performs full-disk observation for every 10 minutes and other regional area observation for every 2.5 minutes, with each spectral band. AHI observation data grasp meteorological phenomena and its changes in detail, and provide new levels of products.
