The main objective of this study was to contribute to the understanding of the estimates and spatial analyses of the surface energy fluxes using the S-SEBI algorithm and TM Landsat 5 images, and to validate the measurements obtained at the micrometeorological tower. The study area was the Frutacor farm, with cultivated area of banana crops, adjacent to bare soil and native vegetation areas, located at the irrigation district of Quixeré, in the Low Jaguaribe basin, Ceará State. The S-SEBI algorithm seems to be a good estimator of the surface energy fluxes in agreement to different studies developed throughout the world. The comparison between the S-SEBI and the micrometeorological results showed good agreement, evidencing that the S-SEBI algorithm is a promising tool in obtaining the spatial distribution of the surface energy fluxes over semi-arid regions.
