Current models of stochastic clouds are briefly overviewed. Generalized formulas of the method of closed equations are presented; they are designed for calculation of mean fluxes and brightness fields in the statistically homogeneous model of broken clouds, taking into account the molecular absorption and interaction of radiation with aerosols and underlying surface. The approach is described, developed for reduction of the laboriousness of computations of mean spectral fluxes in the near-IR wavelength range 0.7-3.6 µm, which combines methods of closed equations and dependent tests. Mean flux calculations in the statistically homogeneous Poisson cloud model are compared with results of simulation in fractionally integrated cascade and Gaussian models of broken clouds, earlier validated against realistic subgrid-scale cloud structures.
