中文摘要: 通过对MODIS反演的地表温度与四川盆地自动气象站观测的准同步地面空气温度Ta和0 cm地温Ts的相关分析，结果表明：对于非均匀下垫面，卫星反演地表温度TLS分别与Ta和Ts的相关系数稳定性都不好，不同卫星过境时间的相关系数差异很大。但（Ts-TLS）与（Ts-Ta）却有着既显著又稳定的线性相关，不同卫星过境时间的相关系数都达到0.8以上，具有良好的相关性。基于卫星反演地表温度和空气温度的地温统计模型，其标准误差为4.85 ℃。
中文关键词: 卫星反演地表温度， 空气温度， 地温， 相关分析
Abstract:The correlations between synchronized air temperature (Ta) and soil temperature (Ts) at automatic weather stations and the land surface temperature (TLS) retrieved from MODIS are analyzed. The results show that for inhomogeneous land surface the correlation coefficients between TLS) and Ta and Ts are unstable, and the correlation coefficients at different satellite passing through time have a great difference. But there is a stable linear correlation between (Ts-TLS)) and (Ts-Ta), and the correlation coefficients at different satellite passing through time are greater than 0.8. A regression equation of soil temperature depending on TLS) and Tais obtained and its standard error is 4.85 ℃.
