Figure 1.

Black lines show the radiance simulations, while the MODTRAN4 reference calculations are given by colored lines with circles. (a) Influence of AOD ${\tau }_{550\mathit{\text{nm}}}^{\mathit{\text{aer}}}$ on the observed path-radiance $({\rho }_{\lambda }^{\mathit{\text{sfc}}}=0)$ with the single scattering approximation $(L_{550nm,\mathit{\text{SSA}}}^{\mathit{\text{atm}}})$ from Equation 3 and with multiple scattering $(L_{550\mathit{\text{nm}}}^{\mathit{\text{atm}}})$ from Equation 5. (b) Influence of ${\tau }_{550\mathit{\text{nm}}}^{\mathit{\text{aer}}}$ on the observed radiance $(L_{550\mathit{\text{nm}}}^{\mathit{\text{sensor}}})$ including the surface contribution from Equation (8). ρ = ‥% denotes the corresponding surface reflectance ${\rho }_{\lambda }^{\mathit{\text{sfc}}}$.
