ABSTRACT
This chapter analyzes the “single-source surface energy balance algorithm for land (SEBAL)” the “two-source energy balance (TSEB) modeling scheme” and the “simplified-surface energy balance index (S-SEBI)” and compared with each other to model surface energy fluxes in an agricultural area characterized by typical Mediterranean crops. A detailed description of the SEBAL and TSEB models can be found, respectively, in the work of Bastiaanssen et al. and of Norman et al. and Kustas and Norman. The first comparison between the two models in the same study area can be found in the work of Ciraolo et al. The chapter describes only the main differences of the models, with particular attention to the sensible heat flux computation. The remotely sensed imagery was collected during two distinct periods—in the spring and summer of 2005 and 2008. In particular, between June and October 2008, seven high-resolution airborne images were acquired at a height of about 1000 m above ground level.
