A modeling study of the total irradiation reaching a tilted surface facing towards the Equator at a place with the same latitude (-22.85°), using the Daily partitioning energy, is presented. In this study three total ...

Three methods will be used to evaluate the surface global irradiance: radiative transfer theory, empirical regression, and artificial neural networks (ANN). Radiative transfer is the fundamental theory that describes the ...

This paper presents a climatic and statistical analysis of global, direct horizontal and diffuse radiation from a database of solar radiation measured from 1996 to 2006 in the city of Botucatu, SP, Brazil. Variation intervals ...

This study aims to determine the effectiveness of two methods of correction of diffuse irradiance measured with shadowbands: LeBaron-Perez method and Dal Pai-Escobedo method. For the LeBaron-Perez method, we use the original ...

On June 4th, 2011, the Puyehue-Cordon Caulle volcanic complex (40ª35´25′′S 72ª07´02′′W, Chile) started eruption, sending ash 45,000 feet into the atmosphere. After the initial period, the eruption continued for several ...
