Abstract
It is a great challenge to accurately reveal their relationship for both SAT estimation from LST and LST validation with SAT. Bivariate correlation and regression analyses were used to investigate the relationships between the LSTs retrieved from the Landsat thermal infrared (TIR) images and the synchronous hourly SATs acquired at weather stations in this study. Results show that at the significance alpha = 0.05 level (1) there is no statistically significant correlation between the LST and any one of the SAT or height corrected SAT variables for the two seasons, (2) it is very likely that there is no prepositional effect or lagging effect of the correlation between the LST and any SAT or corrected SAT for the two seasons, (3) there is no pronounced linear regression trend between the LSTs and the SAT variables during both spring 2008 and fall 2009 seasons significantly, and (4) there is no topography or land cover effects on the correlations between the LSTs and the SATs. The findings suggest that it could be very unlikely and unsuitable to derive surface air temperatures directly from Landsat thermal infrared images due to their uncertain correlations at the significance alpha = 0.05 level.
