【摘要】 根据多次散射理论—离散纵标法 ,将极轨卫星产品资料 ( TOVS资料 )作为初始资料 ,利用中分辨率大气传输模式 MODTRAN3分别计算出晴空和有云情况下5个层次的观测波段的太阳直接辐射和散射辐射 ,与国家一级探空站探测的大气温、湿廓线计算出的辐射值进行比较。发现晴空状况下基本一致 ,有云时存在一定误差 ,表明由卫星的 TOVS资料估算我国东部地区的晴空辐射资料 ,可以弥补我国辐射资料的不足。更多还原

【Abstract】 Based on discrete ordinate method radiative transfer in multiple scattered theory,the solar direct and scattered radiation with observational spectrum(0.29～3.0μm) on 5 layers have been computed using medium resolution atmospheric transfer model(MODTRAN3) and the Tiros Operational Vertical Sounder(TOVS) data for clear/cloud sky over southeast China.There exits some errors between the computed values of solar direct and scattered radiation derived from TOVS and those from radiosond data.The purpose of this study is to show if the satellite measurements(TOVS data) can be directly used to estimate spatial and temporal distribution of solar radiation with observational spectrum.更多还原
