In order to know the energy production of photovoltaic modules, it is necessary have an idea spectral distribution solar radiation, because each technology characterized by a different resolution. The objective this work determine irradiance in ultraviolet, visible, and infrared from triangular shape global spectrum for any sky state. According statistical indicators, coefficient determination ...

Estimation of latent heat flux at the agricultural field scale is required for proper water management. The current generation thermal sensors except Landsat-8 provide data on the order of 1000 m. The aim of this study is to test three approaches based on contextual models using only remote sensing datasets for the disaggregation of latent heat flux over India. The first two approaches are, res...

High quality data of surface radiation is a prerequisite for climate monitoring (Earth radiation budget) and solar energy applications. A very common method to derive solar surface irradiance is the Heliosat method, a one channel approach for the retrieval of the effective cloud albedo (CAL). This information is then used to derive the solar surface irradiance by application of a clear sky mode...

The estimation of solar radiation intensity has been a focus many researchers due to the cost setting up its actual measurements. While them employed empirical models, this study utilizes artificial neural network for analysis and global over two Nigerian cities. model developed using sunshine hours, temperatures relative humidity were compared with existing models. Model performance indicators...

Polarized light provides the most reliable source of information at our disposal for diagnosing the physical properties of astrophysical plasmas, including the three-dimensional (3D) structure of the solar atmosphere. Here we formulate and solve the 3D radiative transfer problem of the linear polarization of the solar continuous radiation, which is principally produced by Rayleigh and Thomson s...

The numerical investigation of computing the rate of radiated solar-energy requires equations as a function of solar-time according to the radiation angle of the sun (β) in the latitude 37°N and the shape. This paper implements the Lagrange interpolation to obtain the equations of normal diagram of elements based on data obtained from surveying. Also the method of Hann-window equation ...
