Abstract
Se ha logrado modelar el perfil de irradiancia solar ultravioleta usando el método Monte Carlo como simulador de la dispersión de fotones en una atmósfera esférica y homogénea. Hipotéticamente, se considera que la irradiancia relativa (adimensional y normalizada a la unidad) está asociada principalmente a la dispersión de Rayleigh y a la geometría atmosférica en tanto que la magnitud irradiativa requeriría un tratamiento más detallado (y la inclusión de otros fenómenos, como la absorción de fotones). Se detalla el fundamento teórico usado para los algoritmos de cómputo, los cuales son lo suficientemente flexibles como para permitir "experimentos" con variación de los parámetros principales; incluyendo también una atmósfera exponencial, orientada, sobre todo, al análisis comparativo.
A simulation of the ultraviolet solar irradiance profile, studying the dispersion of photons in a spherical and homogeneous atmosphere, was realized using the Monte Carlo method. Hypothetically, relative irradiance (dimensionless and normalized to the unit) has been principally associated with Rayleigh's dispersion theory and atmospheric geometry. A more detailed analysis of the radiative magnitude is required (and the inclusion of other phenomena, such as photon absorption). The present study describes the theoretical framework used in the calculation of the algorithms. The data is sufficiently versatile allowing for comparative analysis experiments that vary the principal parameters and include factors such as an exponential atmosphere.
