Abstract
Urban air quality is one of the greatest global issues that affect human health, environmental sustainability, and economic development. In light of this, the aim of this review paper is to describe the latest advancements in air quality monitoring technologies, the use of Geographic Information Systems (GIS) in air quality assessment, and the effectiveness of several methods in understanding and mitigating urban air pollution. Traditional air quality monitoring, which relies on FRM and FEM equipment, provides high-quality data but suffers from high costs, limited flexibility, and spatial coverage gaps. Mobile air quality monitoring and low-cost sensors offer greater spatial resolution but face challenges in data accuracy and temporal coverage. Satellite-based monitoring complements ground-based systems, providing a broader geographic perspective but with limitations in accuracy and temporal resolution. GIS plays a vital role in air quality assessment by conducting spatial analysis, tracking emission sources, and creating complex maps of air quality detail to inform urban planning or policy development. This report also covers the integration with real-time monitoring data and whether it can be used toward decision-making in urban air quality management. This review emphasizes the possible potential of a more inclusive and dynamic approach in urban air quality management that might contribute to healthier and sustainable cities. It ends the paper with the challenges and future directions in the case of urban air quality monitoring such as the need for an easily accessible, scalable, and accurate monitoring system with respect to the increasing urban problem of pollution.
