摘　　要：利用地基MAX-DOAS仪器在2016年9—11月对淮北进行监测,获取NO2垂直柱浓度的时间序列并与OMI卫星进行对比.结果表明,在晴朗天气下两者具有较好的一致性(R2=0.804 6),在晴朗和阴天条件下卫星测量结果系统性低于MAX-DOAS结果,这主要是因为两种仪器观测方式和观测区域不同导致的.9—11月NO2月均值逐渐增加,其中11月的NO2相比9月的增加36.8%,说明淮北地区空气污染在观测时段内加重.研究结果表明,地基MAX-DOAS系统不仅可以对区域污染的演变进行研究,也能够为卫星结果提供验证.The time series of the vertical column density of NO2 in Huaibei area was measured by the ground-based MAX-DOAS instrument from September to November in 2016. The MAX-DOAS result was compared with OMI result and the comparison showed a good consistency in sunny weather （R2 =0.804 6）. It is found that the satellite measurements are less than the MAX-DOAS results in both clear and cloudy weath- er conditions, which is mainly due to the differences between the observation modes of the two instruments and the observation area. The monthly average of NO2 gradually increased from September to November, and NO2 VCD in November had an increase of 36.8% than that in September, indicating air pollution in Huaibei was aggravating during the observation period. The research showed that the foundation MAX-DOAS system could study the evolution of regional pollution and provide validation for satellite results.
