车载被动差分吸收光谱在城市道路空气污染监测中的应用

初步探索了一种基于自然光源的移动式车载被动差分光学吸收光谱仪测量系统，并在对合肥市区道路空气污染监测的实验中得到成功应用。该系统采用天顶散射光被动差分吸收光谱(DOAS)技术对道路上方空气污染进行采样分析，同时结合GPS接收机采集实时经纬度坐标。通过时间信息对两者进行关联，利用GPS接收机定位坐标，并结合合肥市交通地图，依据光谱反演污染气体NO2的柱密度结果绘制整个城市道路上方污染气体浓度图。实验监测路段的NO2垂直柱密度与背景点(解放军电子工程学院校园)监测值之差为6.4×1014 molecule/cm2-1.96×1016 molecule/cm2，由于受到车辆类型、车流量等因素的影响，监测路段总体呈现东北方向平均浓度高于西南方向。

Abstract

A mobile vehicle-borne monitoring system,passive differential optical absorption spectroscopy which is based on natural light sources,has been explored and applied successfully in the experiment of traffic air pollution monitoring in Hefei. The system uses passive zenith-sky scattered light differeential optical absorption spectroscopy (DOAS) to sample and analysis the air on the top of the road,combining with real-time GPS receiver to acquire latitude and longitude coordinates. According to the GPS positioning coordinates in the Hefei traffic map and the NO2 vertical column density retrieved from the spectrum,a overall air quality map will be produced. The difference of NO2 vertical column density between the monitoring road section and the background (IEE of CPLA) is 6.4 × 1014 molecule/cm2 -1.96 × 1016 molecule/cm2. Due to the effects of vehicle type,traffic and other factors,the overall average concentration of northeast section is higher than southwest.
