GCOM-C/SGLI L3 Binned Shadow index (SI) (8-Days,1/24 deg)

GCOM-C/SGLI L3 Binned Shadow index (SI) (8-Days,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 8 days 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 8 days, also 1 day 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 分箱阴影指数（SI）(8天，1/24度)由搭载于GCOM-C卫星上的SGLI传感器获取，并由日本宇宙航空研究开发机构（JAXA）生产。GCOM-C为太阳同步次回归轨道卫星，于2017年12月23日发射，搭载SGLI并执行长期全球观测，涉及28项与全球气候系统相关的地球物理变量，包括大气、陆地、海洋和冰冻圈中的气溶胶和植被。这些数据将有助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3级产品定义为通过对第1B级和第2级产品在时间和空间域内进行统计分析而导出的产品。该数据集为8天分箱统计产品，通过将空间分辨率降低至1/24度并使用EQA投影来生成。本数据集包括SI：阴影指数和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8天，同时提供1天和1个月的统计。投影方法为EQA。生成单位为全球。当前产品的版本为3.版本2亦可供使用。
