【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:0.37kg/s、0.36kg/s,NO₂平均输送通量分别为:0.29kg/s、0.27kg/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。更多还原

【Abstract】 The passive DOAS system,which was installed in a car,was applied in the detection of the urban area and industrial area.The gas column density was obtained by the DOAS fitting process using the zenith scattered sunlight.Chongqing urban area and an industrial area of Chongqing city were measured in our experiments and the distribution and transportation of SO₂,NO₂ in this area was achieved.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.更多还原
