Short summary
Monitoring fine aerosol concentration is important because of the adverse impacts of high fine-particle concentration on human health. However, monitoring fine aerosols is difficult during cloudy and nighttime periods. In this study, an empirical model using measurements from ceilometers was developed to measure fine aerosol mass concentration even under cloudy or nighttime conditions. The findings of this study illustrate the strong need for ceilometer data in air quality monitoring.
