Morfologia urbana e ilhas de calor na cidade de Natal/RN: uma análise a partir de sensoriamento remoto e zonas climáticas locais. 2025. 74 f.

Landsat 8 satellite images were used to generate Surface Temperature (ST) maps and calculate the NDVI and NDBI indices, representing vegetated and built-up areas, respectively. The analysis included the Local Climate Zones (LCZ) classification system, allowing for a detailed description of urban morphology and its impacts on climate. The ST maps identified the main UHI hotspots, while the NDVI and NDBI indices highlighted areas with cooling elements and heat retention, respectively. After cross-referencing the results, two main causes for UHI formation related to urban configuration were identified: extensively built or paved areas and densely urbanized zones with limited ventilation, which promote increased local temperatures. The conclusions emphasize the need to preserve and expand green areas in the most critical zones, as well as the importance of strategic and sustainable urban planning to mitigate UHI effects and promote better thermal comfort quality in the city.Attribution-NonCommercial-NoDerivs 3.0 Brazilhttp://creativecommons.org/licenses/by-nc-nd/3.0/br/Morfologia UrbanaIlha de calorÍndice Normalizado de Diferença de Vegetação (NDVI)Temperatura de Superfície TerrestreZonas Climáticas LocaisÍndice Normalizado de Diferença de Construção (NDBI)Local Climate ZonesNormalized Difference Vegetation Index (NDVI)Land Surface TemperatureUrban Heat IslandUrban MorphologyNormalized Difference Built-Up Index (NDBI)bachelorThesisCNPQ::CIENCIAS EXATAS E DA TERRA
