Abstract
A mobile vehicle lidar system has been developed and applied to detect urban air
quality. On September 21 and 22, 2015, particulate matter observation with mobile
vehicle lidar was carried out in the Binhai New Area of Tianjin. Combined with the
latitude and longitude information acquired by a GPS, the three-dimensional distribution
of the aerosol extinction coefficient was presented in the experimental area.
Furthermore, the source, distribution, and the transportation path of the aerosols in
the area were investigated based on lidar data, local meteorological data, and backward
trajectory analysis. The results show that mobile vehicle lidar can detect the
atmospheric aerosols and reflect the stereoscopic distribution properties of aerosols.
The potential of this vehicle lidar system provides a new scientific basis for the study
of the source, distribution, and transportation of atmospheric particles.
