ADEOS-II/GLI L3 STA Map Cloud Optical Thickness of water cloud by reflection method (16days,1/4deg)

ADEOS-II/GLI L3 STA Map Cloud Optical Thickness of water cloud by reflection method (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 cloud optical thickness of water cloud which is retrieved from a non-absorption channel (channel 13), an absorption channel (channel 30), and a thermal channel (channel 35) are used to derive cloud effective particle radius. This product is the representative values, which are estimated from level 3 binned products and projected onto map. The provided format is HDF. The physical quantity unit is none. The spatial resolution is 1/4 degree and the statistical period is 16 days, also 1month statistics is available. Map projection is EQR. The generation unit is global. The current version of the product is "Version 2".

ADEOS-II/GLI L3 STA 水云反射法云光学厚度数据集（16天统计周期，1/4度空间分辨率）由搭载于先进地球观测卫星二号（Advanced Earth Observing Satellite，ADEOS-II）的GLI（全球成像仪，Global-Imager）传感器获取，由日本宇宙航空研究开发机构（Japan Aerospace Exploration Agency，JAXA）制作。近年来，全球环境变化已成为全球瞩目的热点议题。为厘清此类环境变化的机制，先进地球观测卫星二号（ADEOS-II，发射后命名为“Midori II”）被研发，旨在通过太空遥感技术监测地球环境。Midori II搭载的专用任务载荷可专门解析水能量循环与碳循环过程，有望服务于国际气候变化研究计划。GLI是一款光学传感器，可通过多通道系统观测陆地、海洋、云系等地表反射的太阳辐射，以及用于测量生物相关参数的红外辐射。第二代全球成像仪（SGLI）的幅宽达1600公里。本数据集为水云光学厚度产品，通过非吸收通道（13通道）、吸收通道（30通道）与热红外通道（35通道）反演得到，同时可用于推导云有效粒子半径。该产品为代表性统计值，由Level 3分箱产品汇总得到并完成地图投影。数据集提供格式为HDF，物理量无量纲，空间分辨率为1/4度，统计周期为16天，同时支持1个月统计周期的产品。地图投影采用EQR投影，生成范围为全球，当前产品版本为“Version 2”。
