摘要

城市近地面气溶胶的分布随时空快速变化，常用的地基定点监测只能获取区域内有限位置的气溶胶质量浓度，大致反映区域内气溶胶的分布情况。为确定气溶胶和污染物在城市近地面水平路径上的分布情况，利用微脉冲激光雷达（MPL）、粒子计数器、能见度仪和颗粒物质量浓度监测仪获得的气溶胶数据，根据Mie散射理论建立了气溶胶消光系数、粒子谱分布和质量浓度等参数的数学模型，反演得到了水平路径上的气溶胶质量浓度分布。该方法可以以测量点为中心进行0~6 km的360°的水平扫描，具有监测范围大、分辨率高的优点。最后开展了气溶胶水平分布的实际测量，获得了距离6 km长的水平路径上近地面气溶胶质量浓度的实时分布。这为研究城市气溶胶的污染来源和动态变化提供了有效的数据支持。

Abstract

The distribution of aerosol over urban area is rapidly changed with space and time

thus common ground-based fixed-point monitoring can only obtain the mass concentration of aerosol on measuring points within the region

which roughly reflects the distribution of aerosol in the region. In order to determine the horizontal distribution of aerosol and pollutants over the urban area

based on the data obtained by Micro Pulse Lidar (MPL)

particle counter

visiometer and particle mass concentration detector

a mathematical model in terms of aerosol extinction coefficient

particle spectrum distribution

mass concentration was established according to Mie scattering theory

inverting the horizontal distribution of aerosol mass concentration. Taking the measurement points as the center

the method can implement 360° horizontal scanning over 6 km

which exhibits large monitoring scope and high resolution. Furthermore

the horizontal distribution of aerosol was measured experimentally

obtaining the real-time distribution of aerosol mass concentration over 6 km on the horizontal path. It provides effective data supports for the research of pollution sources and dynamic changes of aerosol in urban regions.
