                         Rio Grande do Sul of southern Brazil suggests that deforestation 
                         and urban developments (i.e. pavements, buildings, roads) 
                         interfere with the thermal quality of its urban spaces. The urban 
                         heat island is already recognized as phenomenon occurring in large 
                         cities. In this study we obtain estimates and evaluate surface 
                         temperature (TS) in urban parks and surroundings inside the Porto 
                         Alegre, using remote sensing data and land-use mapping. The 
                         surface temperatures were obtained by processing the thermal band 
                         of Landsat 7 ETM +, using a simplified energy balance model that 
                         accounts for atmospheric correction and terrestrial surface 
                         emissivity. Analysis of temperature differences in urban parks 
                         (and around) was performed for winter and summer seasons. It was 
                         observed that the temperature tends to increase with the distance 
                         from the parks, towards more urbanized areas. The temperature 
                         differences between the coldest points (inside) and warmer (park 
                         surrounding) was varied between 3.8 and 5.6°C in the winter; and 
                         from 6.2 to 8.6 °C in the summer. The radius of influence of each 
                         park in the TS values was estimated at between 50 and 200m from 
                         the edge, although it depends on particular characteristics of 
                         each park.",
