气象参数估算气溶胶光学厚度方法的实验验证
Experimental verification of aerosol optical depth calculated by meteorological parameters
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。
Abstract
Aerosol optical depths calculated from surface visibility and water vapor pressure are compared with those observed by sun photometers.The precision of calculated aerosol optical depths is evaluated by root-mean-square deviation and relative 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.
