dc.description.abstract | En este trabajo se desarrolló un algoritmo para la estimación de la radiación solar global, para una atmósfera despejada, mediante el modelamiento de las ecuaciones teóricas de transferencia radiativa de onda corta (0,3 µm - 2,8 µm). Se determinaron las transmitancias espectrales de la radiación solar directa, debidas a la dispersión de Rayleigh y Mie. Mediante el software Propiedades Ópticas de Aerosoles y Nubes (Optical Properties of Aerosols and Clouds, OPAC) se calculó la Profundidad Óptica de los Aerosoles (Aerosol Optical Depth, AOD) para cuatro diferentes tipos de atmósferas, indispensable para la determinación del índice de turbidez de Ångström. Así mismo, se calcularon la transmitancias espectrales por absorción de la radiación solar directa, incluyendo aerosoles, vapor de agua, ozono y aire seco (mezcla de gases). El contenido de O3 se obtuvo de los datos diarios existentes en base de datos de la NASA. Para la componente difusa de la radiación solar, se dedujo una nueva expresión para el cálculo de la fracción de la radiación solar dispersada por los aerosoles hacia la superficie terrestre. La comparación estadística entre los resultados obtenidos con el algoritmo desarrollado, los datos medidos de la radiación global (estación Potsdam - Alemania) y los resultados de otros tres modelos radiativos, entre 2012 y 2014, muestra que el nuevo modelo permite calcular los valores horarios de la radiación solar global con suficiente precisión. | spa |
dc.description.abstract | In this work we developed an algorithm to estimate global solar radiation for a cloudless atmosphere, by using the shortwave radiative transfer equations (0.3 µm - 2.8 µm). Spectral transmittances of direct solar radiation due to Rayleigh and Mie scattering were determined. In order to estimate the Ångström turbidity coefficient, the Aerosol Optical Depth (AOD) was calculated for four different types of atmospheres, using the software Optical Properties of Aerosols and Clouds (OPAC). Likewise, spectral transmittances due to absorption of direct solar radiation were calculated, including aerosols, water vapor, carbon dioxide and dry air (mixed gases). The ozone content was obtained from daily data of NASA’s database. For the diffuse component of solar radiation, a new equation was developed for the calculation of the spectral forward scattering fraction. The statistical comparison between the results obtained with the model developed here, the measured global solar radiation data at Potsdam radiation station in Germany and the results of other three radiative models, between 2012 and 2014, shows that the new model allows to calculate the hourly global solar radiation with sufficient precision. | eng |
