Urban air pollution poses a critical challenge due to rapid urbanization, increasing vehicular emissions, industrial activities, and infrastructure expansion. Accurately assessing pollution levels and pinpointing emission sources is essential for effective environmental management. This study integrates advanced remote sensing techniques with cost-effective sensor technologies to monitor air quality in an urban setting. Mobile measurements were conducted on April 18, 2024, using the UGAL MDOAS system and the Sniffer 4D sensor, both mounted on a vehicle. The UGAL MDOAS system employs Differential Optical Absorption Spectroscopy (DOAS) to detect atmospheric trace gases, while the Sniffer 4D utilizes electrochemical sensors to quantify pollutant concentrations. This study focuses on measuring and comparing NO2, O3, SO2, O4 and PM levels from both instruments. The findings contribute to enhancing urban air pollution monitoring by demonstrating the effectiveness of hybrid measurement approaches in identifying pollution hotspots and improving air quality assessments.
