Abstract Computer models that evaluate the formulas of these indices together with environmental factors and human characteristics have been created. Physiological equivalent temperature index and classification summer calculation model used for bioclimatic comfort calculations by obtaining monthly data of General Directorate of State Metrology Stations between 1972 and 2018 in Mersin city center. The results, comfortable monthly intervals, were determined and necessary suggestions were made for the people of Mersin city center in a month. In the calculations, the meteorological parameters such as surface-and-air temperature, wind speed, and relative humidity were taken into consideration. Monthly results show the bioclimatically comfortable area in September and May. There are conditions in Mersin that lead to comfortable perceptions in summer. During the cold period, different levels appear and warm and comfortable thermal conditions are observed. GIS analysis was used to determine the development of thermal perceptions over time. It was calculated between 1972 and 2018. According to these coefficients, there is a tendency to increase in PET values in the regions close to the water in Mersin and to decrease in Mersin, which is the station in rural areas, as a city station. Keywords Bioclimatic comfort . Mersin . Urban city . Urban plan
Introduction Thermal comfort indices play an important role in bioclimatology studies. These indices are based on the measurement of human reactions to meteorological parameters. Nowadays, several thermal comfort indices have been developed using various parameters. There are relatively simple and easy-to-use thermal comfort indices using a few meteorological parameters, as well as more complex indices that include people’s differences in their calculations. With the establishment of cities, energy transfer (radiation, convection, conduction), thermal conditions (specific heat, albedo), humidity conditions (evaporation, precipitation, surface flow), and air circulation systems change. These changes make the difference between cities and the natural environment. Air
