中国及周边地区地表温度年内循环参数集（2000-2023年）

地表温度是地球系统中陆地-大气界面的重要参数，与地表辐射和能量平衡密切相关，广泛应用于冰冻圈、气候学、水文学等地球科学的多个领域。地表温度具有时空异质性，通常通过热红外遥感卫星获取大区域范围的地表温度信息。由于受云、雨等天气状况的影响，加之采样频率、传感器故障、反演算法误差等，导致大...

Land surface temperature (LST) is a crucial parameter at the land-atmosphere interface of the Earth system. It is tightly coupled with surface radiation and energy balance, and is widely applied across multiple subfields of Earth science including the cryosphere, climatology and hydrology. Land surface temperature exhibits spatiotemporal heterogeneity, and large-scale surface temperature information is usually acquired via thermal infrared remote sensing satellites. However, due to the impacts of weather conditions such as clouds and rainfall, coupled with factors including sampling frequency limitations, sensor malfunctions and errors in inversion algorithms, this leads to large-
