Analysis of light scattering by atmospheric particles is useful for studying theappearance of light signals. The spatial distribution of scattered lamplight was calculated by Monte Carlo simulation. Comparison of simulation results with measured values revealed that
1) the simulation results agree well with the measured values,
2) the maximum times of scattering in the simulation must be increased as the optical depth increases, and
3) when simulating airport lights, the maximum scattering times should be about60 for optical depths of up to 10 and calculation error of less than 1%.
