Urban expansion escalates both light and air pollution, posing significant threats to environmental health and energy sustainability. This study presents a spatiotemporal analysis of light pollution in Antalya, Turkey, and explores its relationship to urban air quality. Using ground-based measurements from a sky quality meter (SQM), clouds masks from EUMETSAT, and satellite data from NASA’s Black Marble, a comprehensive analysis of night sky brightness and its long-term trends was conducted from 2012 to 2023. Analysis of annual composites identified specific development projects, such as a new hospital and airport expansion, as major sources of increased brightness, with total radiance consistently rising across all districts, reflecting urban sprawl. The relationship between particulate matter (PM2.5) and satellite-observed radiance was examined using data from four ground-based air quality monitoring stations. Despite filtering for clear-sky conditions and moonlight, no statistically significant correlation was found on monthly or daily timescales. This null result likely reflects the decoupling between surface-based PM2.5 measurements and the vertically integrated aerosol column influencing satellite-observed radiance. Upward radiant flux was also quantified to estimate a lower bound in terms of electric cost. Our findings highlight the impact of rapid urbanization on light pollution and provide a baseline for developing targeted mitigation strategies, while indicating that the interplay with air quality in this region is complex.
