| Definition | A five-channel moderate resolution optical imager designed to carry out meteorological observations for Japan, East Asia, Australia and adjacent areas, by tracking clouds and water vapour features. The imager detects radiation from the visible and infrared spectrum using an off-axis focal telescope with two focal planes and infrared bands integrated into a single sensor assembly. The incident spectrum is then separated into visible and infrared channels by a beam splitter, and the infrared channels are further split into four bands by infrared optical filters. On-board calibration is provided for all bands. JAMI exploits the Nyquist spatial sampling technique. The imager uses the Nyquist spatial sampling technique, and detects radiation within five spectral bands of ranges (0.55 - 0.90) um, (3.50 - 4.00) um, (6.50 - 7.00) um, (10.3 - 11.3) um and (11.5 - 12.5) um. The ground resolution is 1 km for solar reflective band (VNIR) measurements, and 4 km for infrared (IR) measurements. The image frame is 21.4 degrees in longitude, and 23.6 degrees in latitude. The field of view is 0.269 degrees per swath. Flown on Himawari-6 (MTSAT-1R). http://www.wmo-sat.info/oscar/instruments/view/236 | ||
