摘要(Abstract)：

基于SBDART辐射传输模式,利用POM-02型天空辐射计观测和反演获得的气溶胶光学参数计算地面总辐射,并与CM21辐射表的观测结果对比以探讨晴天地面总辐射模拟的误差来源。结果表明:地面总辐射对气溶胶单次散射比和水汽柱含量的敏感性较强,模拟中对这2个因子减少50%会分别造成地面总辐射量增加56.99W/m2和减少25.45W/m2。在准确输入水汽柱含量基础上变换大气廓线对地面总辐射计算结果影响甚微。相关性及多元线性回归分析表明,天顶角、气溶胶单次散射比和光学厚度是地面总辐射相对误差的主要来源。利用上述3个因子建立回归方程,回归结果与地面总辐射相对误差的相关系数为0.486(通过了置信度0.01的显著性检验),说明回归方程能够准确的计算相对误差,利用该方法可以对本站模式计算结果进行修订。
