SUMMARY:

The utilization of new methodologies and technologies in geographical science brings with it a range of possibilities and opportunities for the expansion of discussions within this discipline. Among the fields encompassed by geography, those addressing the analysis of space from a physical geography perspective have brought to the forefront debates and advancements beyond the positivist quantification that has for decades marked academic works. Thus, new avenues are opening up to comprehend and analyze the dynamics and functioning of the urban climate. The application of these new approaches in geographical analysis not only enriches the understanding of urban space but also paves the way for innovative solutions regarding the challenges faced by contemporary cities. In light of this scenario, this dissertation investigates the complex relationship between urban development (addressing this process in the city of Nova Iguaçu, Metropolitan Region of Rio de Janeiro) and climatic dynamics, focusing on an innovative approach to study surface temperature in the city. The study employs aerial thermography with a Remotely Piloted Aircraft System (RPAS) as the primary tool to analyze thermal variations on the surface and their interaction with local atmospheric conditions, aiming to verify whether this tool is promising for future studies on geospatial thermal dynamics (especially the configuration of surface urban heat islands) specifically in the city of Nova Iguaçu - RJ. Based on these assumptions, this dissertation has the general objective of comparing the thermal behavior of two selected areas in the municipality of Nova Iguaçu – Metropolitan Region of the State of Rio de Janeiro, through the use of RPAS equipped with a thermal camera and meteorological stations to investigate atmospheric and surface temperature, thereby evaluating whether the equipment contributes to the study of surface urban heat islands. The selected areas were: the Multidisciplinary Institute of the Federal Rural University of Rio de Janeiro (IM UFRRJ) and the Mestre Hiran State School. As a result, the research conclusively demonstrated the applicability and potential of aerial thermography with RPAS as an effective tool for the analysis of surface thermal dynamics in the urban context of Nova Iguaçu. The methodology employed allowed not only the identification of surface temperature variations with high spatial resolution, revealing thermal heterogeneities in different areas of the city, but also the establishment of a significant correlation with atmospheric temperature data obtained by meteorological stations. The results confirm the capability of RPAS equipped with thermal cameras to complement traditional information, offering a spatially detailed overview of temperature distribution, crucial for the understanding and monitoring of the surface urban heat island phenomenon. In summary, the investigation achieved its objectives by integrating concepts from urban climatology, thermal physics, meteorology, and geography, providing a robust foundation for the study of urban climate. The comparison between surface thermal data and atmospheric measurements in the areas of the UFRRJ Campus and the Mestre Hiran State School corroborated the viability of the methodology for future, more in-depth analyses.
