520			_aThis study examines the effects of thermal inversion on air pollution in Adana, Turkiye, with a particular focus on three critical pollutants: Particulate Matter (PM10), Carbon Monoxide (CO), and Nitrogen Dioxides (NO2). Thermal inversion, a meteorological phenomenon where a layer of warm air traps pollutants near the ground by overlaying a cooler air mass, significantly affects air quality and pollution concentration levels. In Adana, a city characterized by its unique geographical and climatic conditions, thermal inversions are particularly prevalent during the winter months, leading to exacerbated air pollution levels. Through the analysis of air quality data in Adana collected from National Air Quality Monitoring Network of the Turkiye and the vertical temperature data of the same location obtained from Wyoming University, radiosounding database for the year of 2022, this study aims to quantify the impact of thermal inversion events (surface and subsidence inversion) on the concentration of PM10, CO, and NO2. The research methodology includes the use of statistical methods to analyze the correlation between inversion occurrences and pollutant concentration levels. According to the frequency analysis of the days with surface inversions non-inversion days are 131 (35.89%), no data are in 3 days (0.8%), and inversion days are 231 (63.28%). The frequency analysis of the days with subsidence inversion showed that the majority are non-inversion days with 66.57% (243 days), and 33.42% (122 days) are inversion days. The results showed that there is no significant difference in PM10 and CO concentration when examined by depth level of subsidence inversion days, but there is a significant difference in NO2 concentration depending on depth level of the subsidence inversion days. Moreover, when examined by depth levels of surface inversion, it is observed that there is no significant difference in concentration of PM10, CO, NO2 during the surface inversion. Furthermore, when examined by temperature difference level of surface inversion, there is a significant difference in concentration of PM10, CO, NO2 during the surface inversion days. Moreover, when examined by temperature difference level of subsidence inversion, there is no significant difference in concentration of PM10, CO, NO2 during the subsidence inversion days.
