The vereda, typical formation in the Cerrado biome, is recognized for its high-water recharge capacity, due the flat topography, hydromorphic soils and proximity to gallery forests / river courses. Studies in these environments are still scarce, especially those aimed at understanding the dynamics of the radiation and energy balance, related to ecological and climatic processes. The objective of the work is to analyze the energy balance behavior in vereda environments in Northern of Minas Gerais state, in a specific sample area, with advanced remote sensing techniques, applying the SEBAL algorithm (Surface Energy Balance Algorithms for Land). Among the results, it was observed that the behavior of the components of the balance of radiation and energy follow the meteorological and phenological dynamics expected for this phytophysiognomy. In the context of the energy balance, the following average values were obtained, in the winter and summer, respectively: Rn 24 h of 98.71 Wm-2 and 230.95 Wm-2; G of 53.43 Wm-2 and 80.84 Wm-2; H of 26.93 Wm-2 and 88.52 Wm-2; LE of 77.78 Wm-2 and 142.34 Wm-2; and evapotranspiration rate of 2.53 mm.d-1 and 5.02 mm.d-1. The remote sensing techniques used in this study were of great useful for analyzes in veredas, efficiently highlighting the behavior of energy balance and evapotranspiration in this important environment of Cerrado.
