摘要:

采用安装在汽车上的被动DOAS系统对所测城区和污染源进行连续测量。通过DOAS拟合方法处理采集的太阳天顶散射光谱,获得测量点上的污染气体柱密度。通过对重庆城区及重庆某电厂区域的观测实验,获得了重庆市区及所测电厂的SO2、NO2的分布信息和输送情况。在西南、东南风场影响下,所测电厂区域向重庆主城区的SO2平均输送通量分别为:0.37 kg/s、0.36 kg/s,NO2平均输送通量分别为:0.29 kg/s、0.27 kg/s。实验结果表明车载DOAS的光学遥测方法为区域污染气体分布和输送快速测量提供一种有效的手段。

Abstract:

The passive differential optical absorption spectroscopy(DOAS) system, installed in a car, was applied in the detection of pollution source of urban area and industrial area. The gas column density was obtained by the DOAS fitting process using the zenith scattered sunlight. The distribution and transportation of SO2, NO2 in Chongqing urban area and an industrial area of Chongqing City were achieved in the observation experiments of these areas. The influence of emission flux from this industrial area to the main city of Chongqing under the southwest, southeast wind was significant, which was 0.37 kg / s, 0.36 kg/s for SO2 and 0.29 kg/s, 0.27 kg/s for NO2. The experimental results indicated that the mobile DOAS technology was an effective means for the detection of regional distribution and transportation of pollution gases.

Key words: mobile DOAS, regional distribution and transportation, NO2, SO2
