                         use of Earth, resulting from natural and/or anthropic processes. 
                         Many of these changes can be diagnosed from the monitoring of 
                         radiative exchanges that take place at the surface. Net radiation 
                         is an important component of the surface energy balance in 
                         hydrological studies. In spite of existing weather stations in 
                         Brazil, equipped with pyranometers, we cannot forget its size and 
                         that the measures of solar radiation are representative of a 
                         limited area. Because of that, the use of techniques of remote 
                         sensing to complement meteorological information on a certain 
                         place becomes indispensable. In this sense, this study aims to 
                         determine the net radiation at surface, by means of satellite 
                         image covers part of the amazon cerrado, State of Amap{\'a}, 
                         Brazil. A Landsat 5 - TM image obtained in October 26, 2006 was 
                         used to generate map of instantaneous net radiation (Rn) based on 
                         algorithm SEBAL. The instantaneous Rn values varied between 222.73 
                         and 530.0 Wm-2, with average of 376.37 W.m-2. The anthropic areas 
                         showed decrease in net radiation, while forests areas showed 
                         increase. According to the results, it may be concluded that the 
                         methodology used for net radiation determination presented 
                         coherence when compared to other studies in the literature.",
