摘　　要：利用水平能见度和水汽压资料估算气溶胶光学厚度,并和太阳辐射计实测数据对比,用均方根偏差和相对偏差评估估算方法的精度。对气溶胶光学厚度日平均值的分析结果表明:实测值与估算值变化趋势大致相同;估算方法存在系统偏差。提出修正因子对估算方法进行修正,修正后的估算方法精度明显提高。Aerosol optical depths calculated from surface visibility and water vapor pressure are compared with those ob- served by sun photometers. The precision of calculated aerosol optical depths is evaluated by root-mean-square deviation and rela- tive deviation. Analysis of calculated aerosol optical depths shows the existence of systemic errors. A factor is introduced to revise the calculated aerosol optical depths, and comparison of revised and observed aerosol optical depths reveals distinct improvement of calculating precision.
