Abstract :This paper presents an analysis of air pollution in Turkey over a ten-year period. The study was carried out to determine the concentrations of specific pollutants in the atmosphere by analyzing the Sulfur dioxide (SO2), Sulfate (SO4), Organic Carbon Scattering (OCS) and Total Aerosol Angstrom parameter components obtained from MERRA-2 satellite imagery. SO2 and SO4 represent the mass densities of sulphate components in the atmosphere, while organic carbon represents atmospheric carbon scattering. The aerosol Angstrom parameter provides important information on particle size and distribution. The most moderate correlation was found between SO4 and OCS (R value 0.63). Analyzing these parameters is an important step to understand their impacts and changes on air quality in Turkey. Ten years of Land Surface Temperature (LST) data were obtained from Modis images. SO4 was highly correlated with LST (R value: 0.85) and OCS was moderately correlated with LST (R value 0.58). This study aims to analyze the air pollution profile in depth and identify seasonal/long-term trends, focusing on the analysis of long-term data. This analysis provides an important contribution to provide a scientifically based basis for air quality management and environmental policy development.
