| 摘 要： | 2001年1～3月在中国科学院大气物理研究所320 m铁塔10个不同高度(320、240、200、140、100、80、47、15、8 m和地面)使用无动力扩散采样器对SO2和NO2日平均总量及夜间平均浓度进行了观测.结果表明,200m以下高度SO2和NO2浓度较大.北京城区不同高度大气中SO2的浓度1月份最高.NO2浓度1月份和2月份呈现高值.不同高度SO2和NO2浓度与逆温强度有明显的正相关.

| Abstract: | Using non electric sampler for the sample collection, atmospheric sulfur dioxide and nitrogen dioxide have been measured at different altitudes ((320, 240, 200, 140, 100, 80, 47, 15, 8 m and the surface) of the tower in the Institute of Atmospheric Physics from January to March, 2001. The data show that the concentrations of SO 2 and NO 2 were high under 200 m altitudes. The maximum concentration of monthly average SO 2 was in January and the maximum concentration of monthly average NO 2 was in January and February. The positive correlation has been found between the concentrations of SO 2 and NO 2 and the intensity of inversion temperature. |
