GLI
Definition
- The Global Imager, or GLI, is one of the Japan Aerospace Exploration Agency (JAXA) mission instruments on board ADEOS-II which was launched by H-IIA rocket on December 14, 2002. ADEOS-II failed on October 24, 2003. GLI is an optical sensor while will observe globally and frequently the reflected solar radiation from the Earth's surface including land, ocean and clouds. It also has an infrared radiation capability to measure the physical parameters such as chlorophyll, dissolved organic matter, surface temperature, vegetation distribution, vegetation biomass, distribution of snow and ice, and albedo of snow and ice. These data may be used for determining the global circulation of carbon; monitoring clouds, snow, ice and sea surface temperature; and investigating the primary marine production. The GLI will be equiped with 36 spectral channels from visible to infrared wavelengths. The most striking feature of this sensor is summarized below: - The GLI has many more visible channels, especially for the ocean color observations, than other spaceborne sounders or imagers. - Its dynamic range is wide enough to observe land area - It employs 0.38, 0.76, and 1.38 ?m bands that were previously not well utilized for spaceborne remotesensing. - The tilt function enables it to avoid sea reflected sun glitter over middle latitude areas - It has six 250m resolution channels justified to LANDSAT/Thematic Mapper (TM). - Many atmospheric window bands (1.6, 2.2, 3.7, 8.6, 10.9, and 12.0 ?m) are available. - Water absorption bands (6.7, 7.3, and 7.5 ?m) are provided to obtain vertical profiles of water vapor.
