Product Summary

ADEOS-II/GLI L3 Binned Snow grain size retrieved with 1640nm 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 an swath of 1600 km. Snow grain size retrieved with 1640nm is using GLI channel 28 (1.64 μm) independently to retrieve snow grain size at very top surface. Level 2 snow impurities, grain size and surface temperature product (SNGI_p) is used as input data. The physical quantity is micro meter. This product includes sum, square sum, max, min of each pixel is included.
The provided format is HDF. The spatial resolution is 1/12 degree and the statistical period is 16 days, also 1 month statistics is available. Map projection is EQA and PS. The generation unit is Global, North and South Hemisphere. The current version of the product is "Version 2".
