摘要
针对多种气体的同时测量问题,搭建多轴差分吸收光谱测量平台,并使用该测量系统对大气中的二氧化氮、二氧化硫、甲醛、四聚氧等多种气体进行同时测量,获得原始光谱,并对原始光谱采用不同波段进行反演,获得这些气体的斜柱浓度.外场试验表明,多轴差分吸收光谱(MAX-DOAS)同时测量多种气体斜柱浓度是可行的,且数据良好.
For multiple gases measurement problems at the same time,a multi-axis differential absorption spectrum(MAX–DOAS)measurement platform is established in this paper.And the measurement system was used to measure nitrogen dioxide,sulfur dioxide,formaldehyde,tetrameric oxygen and other gases in the atmosphere at the same time.The original spectrum was obtained,and different wavelength bands of the origi?nal spectrum were used for inversion,and the slant column densities of these gases were obtained.The field experiments show that the multi-axis differential absorption spectra(MAX-DOAS)can be used to measure the slant column densities of multiple gases,and the data is satisfactory.
