GCOM-C/SGLI L3 Map Cloud top temperature (1-Day,1/12 deg)

GCOM-C/SGLI L3 Map Cloud top temperature (1-Day,1/12 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 map-projected statistics product. This dataset includes cloud top temperature. The physical quantity unit is Kelvin. The stored statistics values are average (AVE) and quality flag (QA_flag). The provided format is HDF5. The Spatial resolution is 1/12 degree. The statistical period is 1 day, also 8 days 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 云顶温度（单日合成、1/12度分辨率）数据集由搭载于GCOM-C卫星的SGLI传感器获取，由日本宇宙航空研究开发机构（Japan Aerospace Exploration Agency, JAXA）生成。GCOM-C是2017年12月23日发射的太阳同步近回归轨道卫星，搭载SGLI传感器，在大气、陆地、海洋、冰冻圈四大领域内，对包括气溶胶、植被在内的28项与全球气候系统相关的地球物理变量开展长期全球观测。该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。三级产品（Level 3）指通过对一级1B产品（Level 1B）和二级产品（Level 2）在时间与空间域内进行统计处理后得到的衍生产品。本数据集为逐日地图投影统计产品，包含云顶温度参数，物理量单位为开尔文（Kelvin）。存储的统计值包括平均值（AVE，Average）与质量标记（QA_flag，Quality Flag）。数据存储格式为HDF5，空间分辨率为1/12度。统计周期为1日，同时也支持8日和1个月的统计合成产品。投影方式为EQR，数据覆盖全球范围。当前产品版本为Version 3，同时也提供Version 2版本产品。
