MesoStar in collaboration with LAPLACE and CNRM developed tools, based on radiative computations using Mote-Carlo techniques,that allows image rendered of cloudy atmosphere from Large-Eddy simulations.

Several examples below:

BOMEX simulations (small oceanic cumulus) above mountains

ARM simulations (continental cumulus) over a plane surface or mountains

FIRE simulations(stratocumulus)
