ADEOS-II/GLI L3 STA Map Snow grain size retrieved with 865nm band (16days,1/12deg) is obtained from the GLI (Global-Imager) sensor onboard ADEOS-II and produced by the Japan Aerospace Exploration Agency (JAXA). Global environment change has become a worldwide concern in recent years. In order to clarify these environmental changes, the Advanced Earth Observing Satellite (ADEOS-II, renamed "Midori II" after launch) has been developed for the purpose of monitoring the Earth environment using remote sensing technology from space. Midori II carries mission instruments that are particularly dedicated to clarify the water energy cycle and the carbon cycle, and is expected to be utilized for international climate change research programs. GLI an optical sensor that observes the reflected solar radiation from the Earth's surface, including land, oceans and clouds and/or infrared radiation with a multi-channel system for measuring the biological content. The SGLI has a swath of 1600 km. This product includes snow grain size retrieved with 865nm is using GLI channels 5 (0.46 Î¼m) and 19 (0.865 Î¼m) which is based on the principle that the reflectance of snow is known to be dependent on snow grain size in the near infra-red (NIR) range and pollution in the visible range. The physical quantity is micro meter. This product is the representative values, which are estimated from level 3 binned products and projected onto map. The provided format is HDF. The spatial resolution is 1/12 degree and the statistical period is 16 days, also 16 days statistics is available. Map projection is EQR and PS. The generation unit is Global, North and South Hemisphere. The current version of the product is "Version 2".
