中文摘要	基于热传导理论建立土壤日温差模型,可实现基于TM 影像提取特定深度的土壤日温差信息。利用该模型获取的土壤日温差与ATI 的分辨率可达到120 m (TM)或60 m (ETM+)。荒漠矿区实验表明,实测土壤水分与MODIS 得到的ATI 的相关系数仅为0.264,而与改进模型得的高分辨率ATI 相关系数为0.789,监测的土壤水分均方根误差为1.90% (m~3/m~3)。提出的方法同样还适用于其他具有热红外波段的高分辨率影像结合ATI 的土壤水分提取。
英文摘要	A surface soil moisture model with improved spatial resolution was developed using remotely sensed apparent thermal inertia (ATI). The model integrates the surface temperature derived from TM/ETM+ image and the mean surface temperature from MODIS images to improve the spatial resolution of soil temperature difference based on the heat conduction equation, which is necessary to calculate the ATI. Consequently, the spatial resolution of ATI and SMC can be enhanced from 1 km to 120 m (TM) or 60 m (ETM+). Moreover, the enhanced ATI has a much stronger correlation coefficient (R~2) with SMC (0.789) than the surface reflectance (0.108) or the ATI derived only from MODIS images (0.264). Based on the regression statistics of the field SMC measurement and enhanced ATI, a linear regression model with an RMS error of 1.90% was found.
