摘要：

随着全球工业化速度加快和人口的增多，大气环境问题日益突出，NO2和气溶胶在大气化学中扮演着重要的角色。地基多轴差分吸收光谱技术（MAX-DOAS）基于被动DOAS原理，近年来已成功应用于大气痕量气体柱浓度和气溶胶光学厚度（AOD）测量方面。本文基于被动DOAS算法对合肥秸秆燃烧期间NO2柱浓度以及气溶胶光学厚度进行了观测，并把对流层柱浓度和臭氧监测仪(Ozone Monitoring Instrument, OMI)结果进行对比；测量的气溶胶光学厚度和太阳光度计（CE318）进行了对比。结果表明，MAX-DOAS测量结果要高于卫星值，11月6日MAX-DOAS测量NO2柱浓度日均值为OMI的1.9倍；二者在无云条件下一致性较好；MAX-DOAS反演AOD和太阳光度计结果相关性在0.9以上。

Abstract:

With the development of global industrialization and increasing population, the atmosphere environment has been a serious problem. NO2 and aerosols play an important role in atmosphere chemistry. Ground-based multi axis differential optical absorption spectroscopy(MAX-DOAS) has been successfully applied in the measurements of the trace gas vertical column density(VCD) and aerosol optical depth(AOD). NO2 VCD and AOD were measured based on MAX-DOAS in Hefei City during the open stalk burning period. NO2 VCD was compared with the result of OMI, and results of AOD was compared with sunphometer(CE318). It showed that NO2 concentration measured by MAX-DOAS was 1.9 times higher than that of Ozone Monitoring Instrument (OMI), the maximum is 1.9 times the results of OMI, and both instruments had good accordance during clear days. The correlation coefficient between AOD measured by MAX-DOAS and that by CE318 is larger than 0.9.

Key words: multi axis differential optical absorption spectroscopy, vertical column density, aerosol optical depth, sunphotometer
