Abstract:

Numerical simulation of the spatio-angular characteristics of reflected solar radiation in broken clouds is performed in the spherical model of the atmosphere using statistical algorithms developed at IAO SB RAS. The regularities of the formation of brightness fields caused by the finite cloud size, their mutual shading and radiation reflection by neighboring clouds in selected cloud realizations are considered. The spatio-angular features of brightness fields in the realizations with small and medium cloud fraction mainly depend on the location of clouds relative to the viewing direction and direction «to the Sun».

Keywords:

solar radiation, Monte Carlo method, isolated cloud, broken clouds, cloud 3D effects
