| 摘 要： | 介绍了基于太阳散射光的多轴被动差分吸收光谱技术与系统及其在大气污染气体垂直柱浓度监测中的应用．实验中利用夫琅和费光谱作为参考光谱，同时将Ring光谱作为一种吸收结构参与拟合去除太阳光谱中的夫琅和费结构和Ring效应对测量结果的影响，并结合辐射传输模型将污染气体斜柱浓度转换为垂直柱浓度，通过“好运北京”奥运限车期间与OMI卫星的对比实验一致得出限车期间NO2有约20％的下降，证实了本方法的可行性．

| Abstract: | The method and system of determination of trace gas vertical column density by passive MAX-DOAS were described.A so called Fraunhofer spectrum was used as reference spectrum in the DOAS fitting process to reduce the influence of Fraunhofer lines.Ring spectrum was included in the DOAS fitting process as an additional Absorber to decrease the Ring effect.And slant column density was converted into vertical column density by the radiative transfer model.Through compare with Dutch-Finnish nadir-pointing spectro... |
