Abstract

The invention relates to an aerosol particle spectrum distribution fitting method and system based on haze measurement data. The method comprises steps that a laser radar and a solar photometer are employed to respectively measure aerosol optical properties to acquire laser radar data and solar photometer data; the optical thickness of the lower atmosphere is acquired through inversion based on the solar photometer data; an extinction coefficient of the lower atmosphere is acquired through inversion based on the laser radar data; aerosol particle spectrum distribution of the lower atmosphere is acquired through inversion by employing the extinction method based on the optical thickness of the lower atmosphere and the extinction coefficient of the lower atmosphere acquired through inversion. The method is advantaged in that in combination with the measurement data of the laser radar and the solar photometer, atmospheric optical thickness stratification and the extinction method are utilized to retrieve aerosol spectrum distribution characteristics, and a particle spectrum distribution fitting function of the lower atmosphere is acquired.

Description

technical field [0001] The invention relates to the technical field of atmospheric optics, in particular to an aerosol particle spectrum distribution fitting method and system based on haze measurement data. Background technique [0002] Smog is a common weather phenomenon. It is caused by the fact that the total amount of particulate matter and nitrogen oxides contained in the air exceeds the normal level, resulting in cloudy air and reduced visibility. The impact of smog on the atmosphere is directly related to the distribution of its aerosol particles. For haze weather, both the concentration of small particles and the concentration of large particles in the air are much larger than normal weather. Compared with foggy days, the concentration of small aerosol particles in haze days is greater than that in foggy days, and the concentration of large aerosol particles in haze days is much smaller than that in foggy days. [0003] Based on the measured data of the sun photom...
