Broadband solar fluxes and heating rates for atmospheres with 3D broken clouds

A 3D Monte Carlo photon transport algorithm is presented that computes broadband solar fluxes and heating rates. It treats attenuation by cloud droplets and gases separately and can produce 3D distributions of constituent absorptances. Underlying surfaces are accounted for and diurnal-mean calculations can be achieved in the same time as typical single-zenith-angle experiments. Domain-averaged fluxes and heating rate profiles are presented for …
