ADEOS-II/GLI L3 Binned Cloud fraction (1month,1/4deg) 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. The SGLI has a swath of 1600 km. This product is cloud fraction data which classified by the ATSK16 algorithm and cloud property products are used as input. The cloud shape can be determined by sum of spatial differences between each pixel in an area of 1/4 degree x 1/4 degree in Lat. and Lon., so a high difference means cumulus-type and a low one stratus-type. The cloud information can be used for estimation of surface radiation budget as a research product. This product includes sum, square sum, max, min of each pixel is included. The provided format is HDF. The physical quantity unit is None. The generation unit is global. Map projection is EQR. The spatial resolution is 1/4 degree and time resolution are 1month. The current version of the product is "Version 2".
