摘要：

HCHO是城市大气污染物中的重要组分。采用多轴差分吸收光谱仪（MAX-DOAS）于2008年夏季对北京上空对流层HCHO斜柱浓度进行了测量，研究了HCHO差分吸收光谱处理算法，考虑了温度和I0效应对气体吸收截面的影响，并对大气Ring效应进行了校正。采用几何近似的方法计算了对流层大气质量因子（AMF），并将HCHO斜柱浓度转换成垂直柱浓度，得到了实验期间对流层HCHO的垂直柱浓度时间序列，并且HCHO垂直柱浓度早晚比较低，约在中午最高。MAX-DOAS HCHO垂直柱浓度与GOME-2卫星和SCIAMACHY卫星结果具有较好的相关性。

Abstract:

HCHO is an important ambient pollutant in urban areas. Ground-based multi axis differential optical absorption spectroscopy(MAX-DOAS) was used for the measurement of tropospheric HCHO’s slant column density in summer 2008 in Beijing. The cross section’s dependence to temperature, I0 effect and Ring effect correction are performed in the spectrum analysis. Tropospheric AMF is calculated using geometrical approximation method. The tropospheric vertical column density (VCD) is converted from slant column density by AMF, and the variation of HCHO in the experiment period is shown. Compared to GOME-2 and SCIAMACHY's HCHO results, the correlation is evident.

Key words: MAX-DOAS, air mass factor, HCHO
