This study analyzed the influence of the soil s usage and occupation on the surface temperature variance and on radiation balance in Joao Pessoa city. For that, it was used remote sensing techniques, Geographic Information Systems and SEBAL algorithm. For the soil s usage and occupation classification, and the determination of emissivity, albedo, NDVI, IAF and SAVI were used, and for surface temperature and radiation balance, Landsat 5-TM satellite s images was used, referring to november 5, 1991; August 26, 2006; and October 8, 2010.The usage and occupation of João Pessoa s soil analyses showed that during the years of 1991, 2006 and 2010, the city had a considerable increase of the urban mesh above herbaceous vegetation and bare soil. The surface temperature has shown greater values above urban area and bare soil on the last three years, above all on 1991 which obtained maximum temperature values, with average of 31.4°C above urban area and 31.1°C above bare soil. The radiation balance images and statistic values has shown that the highest values of Rn was founded above arboreal/shrubby vegetation and water for all the years, above all on 2010 when was obtained the highest values of Rn for all soil usages, which the averages were 717.5W/m² above water, and 703.2W/m² above arboreal/shrubby vegetation. The relationship between the albedo of soil usages (urban and herbaceous vegetation) with the temperature and radiation balance, has shown that it was satisfactory, indicating the method efficiency for estimate the quoted parameters with the targets analyzed for João Pessoa city. The temperature and radiation balance results found on this study, obtained through SEBAL and satellite images, allows to conclude that the values has shown match variances with those showed in the literature for similar soil usages
