With the rapid development of economy and the process of urbanization, the atmospheric environment presents the characteristics of regional and compound pollution. It is very necessary to grasp the pollution emission and its temporal and spatial distribution information in time to analyze the formation mechanism of air pollution and the dynamic temporal and spatial evolution process of pollutants. Vehicle passive differential absorption spectroscopy (differential optical absorption spectroscopy, DOAS) technology is a new monitoring technology that has emerged in recent years. Based on its technology, it is an optical telemetry method to detect the distribution of polluted gases over cities. The passive DOAS system installed on the car is used to continuously measure the measured city, and the collected solar scattering spectrum is processed by DOAS fitting method to obtain the pollution gas column truss at the measurement point. It has a wide application prospect in pollution emission and pollutant temporal and spatial distribution monitoring.
