GCOM-C/SGLI L3 Binned Shadow index (SI) (1-Day,1/24 deg)

GCOM-C/SGLI L3 Binned Shadow index (SI) (1-Day,1/24 deg) is obtained from the SGLI sensor onboard GCOM-C and produced by the Japan Aerospace Exploration Agency (JAXA). GCOM-C is Sun-synchronous sub-recurrent Orbit satellite launched on December 23, 2017, which mounts SGLI and conducts long-term global observations of geophysical variables related to the global climate system across 28 items including aerosol and vegetation over 4 areas of atmosphere, land, ocean, and cryosphere. The data will be used to contribute to higher accuracy of global warming prediction. The SGLI has swath of 1150 km in the visible band and 1400 km in the infrared band. Level 3 products are defined to be products derived from Level 1B and Level 2 products by statistically processing the Level 1B and Level 2 products in time and space domains.This dataset is daily spatial binning statistics product by reducing the spatial resolution to 1/24 deg with EQA projection.This dataset includes SI: Shadow Index and QA_flag. Physical quantity unit is dimensionless. The physical quantity unit is W/m^2/um/sr. The stored statistics values are average (AVE), root-mean-square (RMS), maximum value (MAX), minimum value (MIN), number of input data (Ninput), number of used data (Nused), date of observation (Date), and quality flag (QA_flag). The provided format is HDF5. The Spatial resolution is 1/24 degree. The statistical period is 1 day, also 8 days and 1 month statistics are available. The projection method is EQA. The generation unit is Global. The current version of the product is Version 3. The Version 2 is also available.

GCOM-C/SGLI L3 Binned Shadow index (SI)（一日，1/24度）数据源于搭载于GCOM-C卫星的SGLI传感器，并由日本宇宙航空研究开发机构（JAXA）制作。GCOM-C为太阳同步次级回归轨道卫星，于2017年12月23日发射升空，装备有SGLI传感器，对全球气候系统相关的地球物理变量进行长期全球观测，涵盖大气、陆地、海洋和冰冻圈四个区域，共计28项指标，包括气溶胶和植被。该数据集将被用于提高全球变暖预测的精确度。SGLI在可见光波段具有1150公里的扫描宽度，在红外波段具有1400公里的扫描宽度。第三级产品定义为通过对第一级B和第二级产品在时间和空间域内进行统计分析而派生出的产品。本数据集为每日空间分箱统计产品，通过将空间分辨率降低至1/24度并采用EQA投影生成。本数据集包括阴影指数（SI）和QA标志。物理量单位为无量纲。物理量单位为W/m^2/um/sr。存储的统计数据包括平均值（AVE）、均方根（RMS）、最大值（MAX）、最小值（MIN）、输入数据数量（Ninput）、使用数据数量（Nused）、观测日期（Date）和质量标志（QA_flag）。提供的数据格式为HDF5。空间分辨率为1/24度。统计周期为1天，同时提供8天和1个月的统计数据。投影方法为EQA。生成单位为全球。当前产品的版本为3.0版，2.0版亦可用。
