In this work, we study the different components of UV Index, direct, diffuse, and global, for seven years erythemal measurements in a Mediterranean locality at Burjassot AtmoSpheric Station (BASS). The have been taken with three YES-UVB-1 radiometers: one provided shadow disk on Sun tracker; radiometer to measure global horizontal radiation; Sun-tracking direct radiation an especially designed ...

Different applications dealing with plant physiology, biomass production and natural illumination in greenhouses require knowledge of the photosynthetically active radiation. In absence of measurements of this flux, one must rely on parametric approaches. In this way, the radiant energy is computed using available atmospheric parameters. In the present work, we have developed a comparison among...

In the Cerrado-Amazonian ecotone in State of Mato Grosso, intensely altered by anthropic action, knowledge and processes energy conversion balance are still incipient, making monitoring modeling diffuse radiation essential for several applications. The objective this study was to evaluate seasonality diurnal evolution estimate hourly (Hdh) incident horizontal plane between June 2011 October 201...

Three methods for analyzing and modeling the global shortwave radiation reaching the earth’s surface are presented in this study. Solar radiation is a very important input for many aspects of climatology, hydrology, atmospheric sciences, and energy applications. The estimation methods consist of an atmospheric deterministic model and two data-driven intelligent methods. The deterministic method...
