description: ADEOS-II/GLI L3 Binned Aerosol Angstrom Exponent (16days,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. 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 is Angstrom exponent data which is an index of aerosol size distribution over ocean surface. Visible (channel 13, 678nm) and near-IR (channel 19, 865nm) channels are used as input to retrieve Angstrom exponent and temporarily and spatially sampled level 2 data. For retrievals, ancillary data are needed, which include wind velocity at 10meter height, ozone and water vapor amount to correct radiance for surface reflectance, ozone and water vapor absorption. This product includes sum, square sum, max, min of each pixel is included. The provided format is HDF. The physical quantity unit is None. Map projection is EQR and generation unit is global. The spatial resolution is 1/4 degree and the statistical period is 16 days. The current version of the product is "Version 2".
