近全球尺度地表短波辐射、光合有效辐射和紫外线辐射数据集(2018.6-2023.12)
收藏资源简介:
全球尺度的高时空分辨率地表辐射数据在太阳能利用、植被光合作用和环境健康等领域具有重要意义。本研究基于4颗静止卫星(GOES-16、FY-4A、Himawari-8 和 MSG-1)构建了融合反演框架,充分利用各卫星的观测范围,实现了全球主要区域(60°N-60°S, 0°-360°)的无缝覆盖,生成了空间分辨率为0.05°、逐小时的地表光合有效辐射(PAR)、紫外辐射-A(UVA)、紫外辐射-B(UVB)和短波辐射(SWR)产品。该产品在精度上与CERES产品相当,并通过更高的空间分辨率实现了对区域和局地辐射分布的精细刻画。
High-spatiotemporal-resolution global surface radiation datasets are of great significance in fields including solar energy utilization, vegetation photosynthesis and environmental health. This study constructed a fused retrieval framework based on four geostationary satellites: GOES-16, FY-4A, Himawari-8 and MSG-1. By fully utilizing the observation coverage of each satellite, the framework achieved seamless coverage of major global regions (60°N–60°S, 0°–360°), and generated hourly products of surface photosynthetically active radiation (PAR), ultraviolet-A (UVA), ultraviolet-B (UVB) and shortwave radiation (SWR) with a spatial resolution of 0.05°. These products have comparable accuracy to the CERES products, and enable fine depiction of regional and local radiation distributions thanks to their higher spatial resolution.
