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NO2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NO2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 difference 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.
