| 摘 要： | 在不同太阳天顶角及不同地表条件下，通过辐射传输计算，考察了大气对NOAA/AVHRR可见和近红外通道辐射强度各向异性转换系数的影响。结果表明，在地表为朗伯面的情况下，大气气溶胶有增强辐射强度的各向异性和改变辐射强度角分布型式的作用。

| Abstract: | Through radiative transfer calculations,the effects of atmosphere on the anisotropic transformation coefficients of reflected solar radiances of NOAA/AVHRR visible and near infrared channels have been investigated for some different solar zenith angles and some surfaces.Under the assumption of Lambert surfaces,the atmospheric aerosol has an effect on enhancing the anisotropy and modifying the pattern of angular distribution of reflected radiances. |
