Abstract

The parallel Monte Carlo algorithms developed for numerical simulation of the polarized radiative transfer in the Earth’s atmosphere are discussed. The results of their testing in the aerosol atmosphere and cloud layer as well as the results of calculation of the Stokes vector in an environment with spatially inhomogeneous clouds are presented. Problems of improving the efficiency of the Monte Carlo simulation by transition from sequential CPU computations to parallel GPU computations are discussed. The acceleration rate of the radiation codes achieved by parallelizing computational algorithms on a graphics processor is given. It is shown that the changeover of computing from conventional PCs to the architecture of graphics processors gives remarkable increase in performance and fully reveals the capabilities of the technology used.
