| 摘 要： | 利用MODIS地表温度反演产品,以青藏高原为研究区域,通过单点、区域、模型3方面来验证MODIS地表温度产品在青藏高原冻土模拟中的适用性.通过69个气象站点观测的地表O cm温度数据与所在位置的MODIS地表温度数据比较,二者在时间序列上的变化趋势基本一致,但是平均误差较大.在区域验证中,实测地表温度数据采用经纬度海拔...

| Abstract: | As a main parameter of energy balance on the earth surface,the land surface temperature(LST) is one of the necessary boundary conditions of a numerical permafrost model,and it is also an important observational item of any permafrost monitoring.Traditionally land surface temperature data are collected from meteorological stations.However,the point observation often cannot represent an areal situation well especially in mountainous areas.With its development,the remote sensing technique increasingly becomes ... |
