Land surface temperature (Ts) is a critical variable for understanding the surface energy exchange between land and atmosphere. Using the data measured from micrometeorological flux towers, three types of Ts, obtained using a thermal-infrared radiometer (IRT), a net radiometer, and an equation for sensible heat flux, were compared. The Ts estimated using the net radiometer was highly correlated with the Ts obtained from the IRT. Both values acceptably fit the Ts from the Terra/MODIS (Moderate Resolution Imaging Spectroradiometer) satellite. These results will enhance the measurement of land surface temperatures at various scales. Further, they are useful for understanding land surface energy partitioning to evaluate and develop land surface models and algorithms for satellite remote sensing products associated with surface thermal conditions.
