Detailed Description

大气校正模型

 

式中,L(λ)是卫星传感器记录的辐射;Lr(λ)是Rayleigh路径辐射;La(λ)是气溶胶的路径辐射;Ls(λ)是发自表面的辐射;t(λ,θ)是从像素点到传感器的漫射投射率;λ是考虑波段的中心波长;θ是表面局部法向与像素到传感器方向间的夹角;其计入了地球类球形状的影响。

  

式中,对Rayleigh散射x=r,对气溶胶x=a;μ=cos θ;μ0=cos θ0,θ0是太阳顶角;E0(λ)是对太阳地球距离变化进行了校正的大气顶部的太阳辐射;Toz(λ,μ,μ0)是下行的太阳辐射和上行的路径辐射穿过臭氧层的透射率;τx(λ)是光学厚度;Ψ-(Ψ+)是后向(前向)散射角;Px(Ψ)是相函数;ρ(λ)是表面反射系数。
