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.
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 intensity of forward-scattered light is measured by the forward-scattering visibility sensor, which determines the extinction coefficient of the air, then the visibility can be obtained.
前向散射能见度仪测量前向散射光强度,确定大气的消光系数,进而获得大气的能见度值。
