                         solar radiation in the atmosphere as a random walk of diffuse 
                         photons among several atmospheric layers. Results are obtained in 
                         terms of absorption probabilities in each layer, at ground and 
                         within sky, allowing for making evident the interactions between 
                         the main atmospheric absorbers (ozone, aerosols and water vapor) 
                         and atmospheric structure. Application of this model to cloudless 
                         situations in the extreme cases of rural environment and high 
                         aerosol load by burning biomass shows good results when compared 
                         with SBDART code (+10 W.m-2 systematic difference), and both 
                         differ from ground measurements of global radiation in about 30 to 
                         50 W.m-2. This difference could be lowered having a better 
                         definition of aerosol load during daytime. Global radiation is 
                         obtained by integration of monochromatic irradiances; it is 
                         observed that ME model performance is five times faster than
