GCOM-C/SGLI L3 Map Photosynthetically available radiation (PAR) (1-Month,1/24 deg)

GCOM-C/SGLI L3 Map Photosynthetically available radiation (PAR) (1-Month,1/24 deg) dataset 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 1 month map-projected statistics product. This dataset includes PAR: Photosynthetically available radiation and QA_Flag. The physical quantity unit is Ein/m^2/day. 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 1 month, also 1 day and 8 days 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 地面反射率光谱数据集由搭载于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）制作。GCOM-C卫星为一颗于2017年12月23日发射的太阳同步亚轨道卫星，装备有SGLI传感器，并对全球气候系统相关的地球物理变量进行长期全球观测，包括大气、陆地、海洋和冰冻圈中的气溶胶和植被，共计28项。该数据集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。L3级产品定义为通过在时间和空间域中对L1B和L2级产品进行统计分析而派生出的产品。本数据集为一个月的地图投影统计产品。数据集包含光合有效辐射（PAR）和QA_标志。物理量单位为Ein/m^2/day。存储的统计数据包括平均值（AVE）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。统计周期为一个月，同时提供每日和八日统计数据。投影方法为EQR。生成单位为全球。当前产品版本为版本3，版本2亦可供使用。
