Assess the spatial variations in the Urban Outdoor Thermal Discomfort Index (UOTDI) for tourists in Tehran metropolis abstract

Human activities that generate heat in urban environments are among the primary factors contributing to the decline in thermal comfort in these areas. This decrease in thermal comfort can negatively impact both the physical and psychological well-being of individuals. Therefore, monitoring, predicting, and analyzing thermal comfort patterns in cities is crucial for improving residents' living conditions and enhancing the experience for tourists. This study aimed to assess the spatial variations in the Urban Outdoor Thermal Discomfort Index (UOTDI) for tourists in Tehran metropolis during the warm season. To achieve this, data from synoptic stations and satellite data and products were utilized. In this study, a Random Forest algorithm was employed as a machine learning model for UOTDI modeling. Environmental parameters and surface biophysical characteristics affecting thermal comfort were used as independent variables in this model, while the UOTDI at synoptic stations was defined as the dependent variable. Results indicated that the minimum, mean, and maximum values of the UOTDI in Tehran metropolis were 13.9 ºC, 19.9 ºC, and 28.9 ºC, respectively. Additionally, 28% of Tehran’s area fell into the class of Comfortable thermal comfort, while 70% was classified as Hot class. Municipal districts 22, 21, 9, 18, 19, and 5 showed higher UOTDI values compared to other districts. This study underscores the concerning thermal comfort situation for both residents and tourists in Tehran metropolis, emphasizing the need for precise planning and the implementation of specific measures to improve these conditions.
