Spatio-temporal Analysis of Sentinel-5P Data of Konya City Between 2019-2021

Abstract

Uncontrolled energy consumption by human beings, such as the increase in the demand for the gases used for heating purposes in houses, the rise in the number of industrial production facilities, and the uncontrollable levels of the gases emitted from the exhausts of motor vehicles, are among the causes that trigger chemical gas formation in the atmosphere. Increases in air pollution threaten people's health and disrupt ecological balances. For this reason, regularly monitoring the amount of pollution and taking the necessary precautions is crucial. In this study, which was conducted for this reason, the state of polluting gases between 2019-2021 in the province of Konya was examined using remote sensing data. The data were obtained from the TROPOMI instrument attached to the Sentinel-5 Precursor (S5P) satellite launched into orbit by the European Space Agency (ESA). Various atmospheric gases (ozone, methane, carbon monoxide, nitrogen dioxide, sulfur dioxide, and formaldehyde) can be detected by the sensors in this device. For this purpose, S5P Level-2 data was accessed via the Google Earth Engine (GEE) platform, and different codes were written to obtain each data. Then, the data collection for the study region was completed. The monthly amount of carbon monoxide, ozone, methane, and nitrogen dioxide gases for the study area between the specified dates are shown in the graphs, and maps are produced for each year. As a result, it has been determined that methane gas is not observed in extensive wetlands and forest areas, and the minimum values of NO2, O3, and CO gases are in the summer months and CH4 gas in the winter months. It has also been determined that the region between the west and the south of the city center is the healthiest region in terms of air pollutant gases.
