Compute solar fluxes for both clear and cloudy atmosphere following Lacis and Hansen (1974). The multiple diffusion is taken into account by an addition method and overlapping between water vapor and liquid water with k distribution method. Some improvements from original version concerns:
- introduction of cloud fraction with hazardous recovering
- introduction of aerosol diffusion in the same way as for cloud droplets but with specific optical properties for aerosols.
