On effects of isolated cloud on irradiance at the Earth's surface in the range of 0.4-0.7 μm: results of numerical simulation

We consider the algorithm and results of numerical simulation of irradiance at the Earth’s surface E in the spectral range of 0.4-0.7 μm in the aerosol-molecular atmosphere and in the presence of isolated cloud. We analyze the differences in the irradiance E in the clear-sky and little cloudy atmosphere in dependence of optical and geometrical parameters of cloud, its position relative to the receiver and the illumination conditions.
