2010-2018青藏工程走廊地表温度数据

地表温度作为地表能量平衡中的主要参数，表征了地气间能量和水分交换的程度，广泛应用于气候学、水文学和生态学等的研究中。在冻土研究中，气候是冻土存在和发展的决定性因素之一，其中地表温度是影响冻土分布的主要气候因子，其影响冻土发生发育以及分布，是冻土建模的上边界条件，对寒区水文过程的研究具有重要的意义。利用Aqua和Terra星白天和晚上的四次观测值求得了年平均地表温度。

Land Surface Temperature (LST), as a core parameter in the surface energy balance, characterizes the intensity of energy and water exchange between the terrestrial surface and the atmosphere, and has been extensively utilized in research domains including climatology, hydrology, and ecology. In permafrost studies, climate is one of the decisive factors governing the existence and evolution of permafrost. Among these factors, land surface temperature is the primary climatic driver affecting permafrost distribution, as it regulates the initiation, development and spatial distribution of permafrost, and acts as the upper boundary condition for permafrost modeling, holding critical significance for research on hydrological processes in cold regions. The annual average land surface temperature was derived from four day and night observations acquired by the Aqua and Terra satellites.
