| 摘 要： | 基于AERONET太湖站2005年9月—2010年9月的太阳分光光度计实测数据，分析太湖上空单次散射反照率（SSA）随时间变化特征以及频率分布特征. 结果表明，SSA的月均最大值、最小值分别为8月的0.95±0.03和12月的0.87±0.03. 季节均值的最大值为夏季的0.94±0.03，最小值为冬季的0.88±0.04；SSA的年均值为0.90. 从频率分布来看，SSA的最高频率分布区间为0.9~0.92. 分析表明，太湖上空存在中度吸收型的气溶胶.

| Abstract: | Based on level-2 data from CE-318 installed at Taihu Lake(one of AERONET sites) from September 2005 to September 2010, variation of single scattering albedo (SSA) with time and the frequency distribution features were analyzed. Maximum and minimum monthly mean values of SSA were observed in August (0.95±0.03) and December (0.87±0.03), respectively. Maximum and minimum of seasonal mean value of SSA were observed in summer (0.94±0.03) and winter (0.88±0.04), respectively. Frequency distribution of SSA shows that the peak value is between 0.9 to 0.92, with a yearly average value of 0.90. The aerosol over Taihu Lake should be classified as moderate absorbing aerosol. |
