Mobile cruise monitoring of particulate matter was conducted over four cities, namely Xi'an, Xianyang, Baoji, and Weinan.
This dataset utilizes the radiative signals generated by the interaction between laser and atmospheric aerosols to obtain the characteristics and spatial distribution information of aerosols. The monitoring is performed with one aerosol lidar, one mobile monitoring vehicle, and two on-site service personnel, carrying out regular cruise monitoring to acquire real-time three-dimensional distribution and source attribution of particulate matter in these four key cities. The instrument employed uses laser as the light source, emitting 532 nm laser beams. The receiving telescope collects the backscattered signals of the laser from aerosol particles, and relevant algorithms are utilized to analyze the properties of aerosol particles, including identifying particulate matter, dust, water clouds, ice clouds, and other categories, as well as parameters such as extinction coefficient, depolarization ratio, wavelength exponent, boundary layer height, aerosol optical depth, and cloud information.
Sampling Locations: Xi'an, Xianyang, Baoji, and Weinan
