In areas with heavy industrial activity and population, controlling air pollution is essential for maintaining a good standard of living. Researchers are drawn to study the behavior of primary and secondary sources to reduce pollution. Kocaeli is one of the good candidates with high population and industrial activities. Thus, the scope of the study consists of the distribution of pollutants in Kocaeli province. The primary objective is to identify the spatial distribution of pollutants emitted into the atmosphere from various sources as well as the approximate height at which they will come to a stop. To achieve the goal, data from the Sentinel-5P satellite and the Marmara Clean Air Center in Kocaeli province were also consulted. Additionally, Arc GIS 10.4 was used for the mapping, and Google Earth Engine was used for processing the satellite data. The investigation has revealed that the coastal belts of the Dilovas, Gebze, and Darca are those with the highest levels of air pollution. Pollutant concentrations in the study region have been concentrated between 0 and 500 meters above the observed aerosol height. It was discovered that there was a positive correlation between nitrogen oxide derivatives, carbon monoxide, and sulfur dioxide after both satellite and ground station data were examined. During the winter, these gases become more dense in the atmosphere, and during the summer, they become less dense. This state is effectively created by convective motions brought on by conditions of rising temperature. Data on the aerosol index and formaldehyde reveal greater values throughout the summer because of photochemical reactions. An improvement in multi-dimensional research would lead to ground-breaking knowledge and better air quality in cities like Kocaeli, which is among the first in terms of industry and population.
