| Sumario: | Literature on the propagation of light in turbid media has been thoroughly explored, so an existing visible radiometric propagation model based on Mie theory is improved, and it implies a progress towards a model for the propagation of light in turbid media with irregular particles. Radiation fog, biomass burning, and transported desert dust, have been characterized, and phase function, asymmetry parameter (g), single scattering albedo (SSA) and radiative transfer have been evaluated. According to the results obtained, refractive index, particle density, size distribution (which appeared to fit a log-normal), g, and SSA, have proved to be key parameters in the development of the radiometric calculation. For future work, the implementation of a method capable of reproducing the aerosol optical properties of non-irregular particles (e.g., T-matrix method) is encouraged as well as the experimental validation of this model. |
