Abstract
Surface temperature is one of key physical variables in estimating surface heat fluxes using heat budget method. Therefore, a lot of researches have estimated heat fluxes using thermal-infrared remote sensing data of the 8∼14μm atmospheric window region, namely, thermal-infrared temperature. In this paper, we focus on issues which have occured in investigating the relationship between thermal-infrared temperature and sensible and latent heat fluxes, especially over vegetated surfaces as well as some solution to the issues. Additionally, methods for the atmospheric correction and emissivity correction are described. The former often comes up to problems especially in satellite remote sensing. Combination of remote sensing and numerical models, which is expected to be developed in the near future, is briefly described.
