摘　　要：根据光的多次散射理论的离散纵标法 ,利用我国东南沿海地区探空站的资料 ,计算出不同高度上分谱段的太阳直接辐射和向上、向下散射辐射 ,与相应时刻的卫星测值 (可见光、红外通道 S- VISSR计数值 )进行逐步回归拟合 ,建立晴空状况下卫星测值与大气中各高度太阳直接辐射和散射辐射的统计模式 ,并将拟合方程进行稳定性检验。Based on discrete ordinate method of radiation transfer in multiple scattering and emitting layered media, computations of solar direct and scattered radiation have been done using the radiosonde observations in southeast of China.Values of solar direct and scattered radiation at different heights have been evaluated in spectral bands.The computed values are then used to set up the statistical relationships with simultaneous satellite observations in VIS/IR.Thus conveniently satellite observed data in the VIS and IR channels may be used to estimate the spatial and temporal distribution of solar direct and scattered radiation in cloudless atmosphere.
