Türkiye has its share of pollutant sources stemming from industrialization, urbanization, and increased fuel consumption in both residential areas and industrial plants. The area is significantly impacted by dust transport, given its strategic location at the intersection of Asia, Europe, and Africa. Therefore, it is crucial to analyze air pollutants over the country. PM2.5 (particulate matter with a diameter ≤ 2.5 µm), a crucial element of air pollution, is strongly associated with detrimental effects on human health. However, the study of air pollution and its impact on various societal issues is hindered by limited surface measurements and inadequate spatial resolution in monitoring. In this study, spatiotemporally continuous aerosol diagnostic products such as surface mass concentrations of dust, sea salt, black carbon, organic carbon, and sulfate from the Version 2 Modern-Era Retrospective Analysis for Research and Applications (MERRA-2) were used to evaluate hourly PM2.5 concentrations and its components at 14 major cities (Istanbul, Ankara, Izmir, Adana, etc.) for 2015–2023 in Türkiye. The most populated and industrialized cities were selected for analysis. This study is the first analysis of the MERRA-2 PM2.5 concentrations and its components over major cities in Türkiye. The results indicated that PM2.5 values have been observed to be higher over the city centers located in the southeastern part of Türkiye. Sulfate aerosols are mainly dominant in industrialized cities; however, higher dust concentrations were observed in cities located in the southern part. Relatively higher sea salt particles were found along coastal areas mainly in autumn and winter. However, dust is most obvious in spring and autumn. Overall, our evaluation reveals that our results could be helpful in long-term air quality modeling studies that will be carried out in the most populated city centers in Türkiye.
