GCOM-C/SGLI L3 Map Atmospheric corrected reflectance(SLZI) (8-Days,1/24 deg)

GCOM-C/SGLI L3 Map Atmospheric corrected reflectance (SLZI) (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 map-projected statistics product. This dataset includes solar zenith angle of IRS sensor. The data unit is degree. The stored statistics values are average (AVE) 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 EQR. The generation unit is Global. The current version of the product is Version 3. The Version 2 is also available.

GCOM-C/SGLI L3级大气校正反射率（SLZI）（8日合成、1/24度分辨率）数据集，源自搭载于全球变化观测卫星C（Global Change Observation Mission-C, GCOM-C）的SGLI传感器，由日本宇宙航空研究开发机构（Japan Aerospace Exploration Agency, JAXA）制作。该卫星于2017年12月23日发射，为太阳同步近回归轨道卫星，搭载SGLI传感器，针对大气、陆地、海洋、冰冻圈四大领域，开展与全球气候系统相关的28项地球物理变量长期全球观测，观测内容涵盖气溶胶、植被等。本数据集可用于提升全球变暖预测的精度。SGLI传感器的可见光波段幅宽为1150千米，红外波段幅宽为1400千米。L3级产品（Level 3 products）指通过对L1B级产品（Level 1B products）与L2级产品（Level 2 products）开展时空域统计处理得到的衍生产品，本数据集为8日合成的地图投影统计产品。本数据集包含IRS传感器的太阳天顶角，数据单位为度。存储的统计值包括平均值（AVE）与质量标记（QA_flag）。数据存储格式为HDF5，空间分辨率为1/24度。统计周期为8日，同时支持1日与1月的统计合成产品。投影方式为EQR，生成范围为全球。当前产品版本为V3版，同时也提供V2版数据集。
