大气气溶胶对大气辐射和光传播具有重要影响，而标高是反映气溶胶高度分布特征的关键参量。利用连续光谱的太阳辐射计和前向散射能见度仪，测量了大气柱光学特性以及近地面层的大气水平消光系数，获得了可见光波段的大气气溶胶标高的变化特征：随着波长值的增加，气溶胶标高减小；对于实验当地的情况，一般冬季气溶胶标高要大于夏季的气溶胶标高。

The atmospheric aerosol has important influence to atmospheric radiation and light propagation,but scale height is the key parameter which reflects aerosol height distribution. So using continuous spectrum sun-photometer and forward scatter visibility sensor, we measured the atmosphere column optical characteristic and plan extinction coefficient on earth on the base of two experiments, respectively. The characteristic of aerosol scale height of visibility light-wave is obtained: with wavelength increasing, aerosol scale height declines;generaly, aerosol scale height in winter is higher than it is in summer for the place of experiment condition;the more wavelength is high, the more aerosol scale height is little.
