Modeling of the Global Daily Horizontal Solar Radiation Data over Togo

Estimating and modeling monthly mean daily global solar radiation on horizontal surfaces using artificial neural networks

In this study, an artificial neural network based model for prediction of solar energy potential in Kerman province in Iran has been developed. Meteorological data of 12 cities for period of 17 years (1997–2013) and solar radiation for five cities around and inside Kerman province from the Iranian Meteorological Office data center were used for the training and testing the network. Meteorologic...

Estimation of the Global Horizontal Solar Radiation in Iraq

The aim of this work is to obtain an empirical simple equation to estimate the global horizontal solar radiation (GHSR) as a function of the latitude only. Therefore three empirical models proposed to estimate the GHSR using 17 different locations across Iraq. The models formulated as: Quadratic, 2nd Fourier and 2nd Gaussian expression. The simply input feature beside a fine predictive ability ...

Effect of Estimated Daily Global Solar Radiation Data on the Results of Crop Growth Models

The results of previous studies have suggested that estimated daily globalradiation (RG) values contain an error that could compromise the precision of subsequentcrop model applications. The following study presents a detailed site and spatial analysis ofthe RG error propagation in CERES and WOFOST crop growth models in Central Europeanclimate conditions. The research was conducted i) at the ei...

Regression Modeling of Mean Daily Global Solar Radiation in Al-Ain, UAE

Statistical Modeling of Spatio-Temporal Variability in Monthly Average Daily Solar Radiation over Turkey

Though one of the most significant driving forces behind ecological processessuch as biogeochemical cycles and energy flows, solar radiation data are limited or non-existent by conventional ground-based measurements, and thus, often estimated from othermeteorological data through (geo)statistical models. In this study, spatial and temporalpatterns of monthly average daily solar radiation on a h...
