中文摘要：

利用地基多轴差分吸收光谱仪（multi axis differential optical absorption spectroscopy,MAX—DOAS）在2008年北京奥运期间对奥运场馆附近上空对流层N02进行监测，并与OMI的测量结果进行对比。结果显示：地基MAX—DOAS的N02结果比OMI结果高，最高达到了2．4倍；二者在无云条件下得到了比较好的相关性（R=0．64），但在阴雨天气条件下，云的存在使得MAX—DOAS结果与OMI卫星数据产生了很大差别，其相关系数仅为0．19，但与LP．DOAS却有很好的一致性，相关系数为0．92。

Abstract： The tropospheric nitrogen dioxide over the Olympic venues in Beijing was measured by ground- based multi axis differential optical absorption spectroscopy （MAX-DOAS） during the Olympic Games in 2008, and was compared with the result of OMI. It showed that the result of MAX-DOAS was higher than that of OMI, the maximum is 2.4 times the result of OMI; both instruments had good accordance（R=0.64） when it＇s clear, and when it was rainy or cloudy there was more different between the results of both instruments for the existing of cloud, with a correlation coefficient of 0.19, but the result of MAX-DOAS had better accordance with LP-DOAS, with a correlation coefficient of 0.92.
