| 摘 要： | 通过对2004年秋冬季(9—12月)4次雾霾天气过程在京、津背景地区——北京上甸子大气本底污染监测站观测的大气气溶胶光学特性的分析,发现该地区气溶胶光学特性受天气过程的影响很大。4次雾霾影响时段,平均气溶胶散射系数σ_(sca)、吸收系数σ_(abs)和单次散射反照率ω都远高于雾霾过后清洁时段的数值,其中气溶胶ω在雾霾影响时段为0.94～0.97,雾霾后为0.84～0.86,平均减小了0.1左右,表明雾霾天气有利于气溶胶的累积和生成。相比于光吸收性气溶胶,雾霾天气对光散射性气溶胶的增加更为有利,反映了二次气溶胶的产生及其对消光的贡献可能有较大增加。

| Abstract: | The Northern China is one of the regions with the high incidence of fog and haze.With the rapid development of economy in the recent years,the anthropogenic pollutants,such as aerosol and its precursors have brought about serious visibility degradations in the regions.In the fall of 2004,several heavy fog and haze episodes with visibility less than 1 km are observed at Shangdianzi(SDZ) Atmospheric Background Station.During the fog and haze periods,aerosol scattering and absorption coefficients are measured ... |
