摘　　要：摘,,要:利用太阳直射光谱仪采集的太阳直射光谱进行测量反演,得到大气和气溶胶的光学厚度,再利用Junge分布,对气溶胶光学厚度进行反演计算,获得了对应天气状况下的大气能见度值。分析结果表明气溶胶光学厚度随天气状况变化较大,在能见度较小的情况下气溶胶随波长增加而增大,在能见度较大的情况下气溶胶随波长增加而减小。Measure of direct solar radiation spectrum inversion to get the atmospheric general optical thickness and aerosol optical thickness, distribution and use the Junge, inversion was carried out on the aerosol optical thickness calculation, obtained the corresponding values of atmospheric visibility weather conditions. Analysis results show that the aerosol optical thickness changing with weather is bigger, in the case of visibility smaller aerosol increases with increasing wavelength, and in the case of greater visibility aerosol decreases with the increase of the wavelength.
