This paper proposes the modeling and simulation of the incident solar radiation on a horizontal and inclined plane in the city of Agadir. To do, we adopt the Kasten model which takes the atmospheric turbidity into consideration in order to estimate the incidental solar radiation on a horizontal plane. In addition we determine the incident solar radiation on an inclined plane from the global hor...

Plant ecologists have recognized the importance of solar radiation for decades but have difficulty measuring it on plots. Proxies recorded on the ground or geographical information system (GIS) indices processed with a digital elevation model (DEM) have generally been used. Here we compare the efficiency of different methods of estimating spatially distributed topographic solar radiation, from ...

Measurement and modeling of broadband and spectral terrestrial solar radiation is important for the evaluation and deployment of solar renewable energy systems. We discuss recent developments in the calibration of broadband solar radiometric instrumentation and improving broadband solar radiation measurement accuracy. An improved diffuse sky reference and radiometer calibration and characteriza...

Seven empirical models and the artificial neural network model (ANN) are applied and validated to estimate the daily and monthly global solar radiation on a horizontal surface in Qena, Upper Egypt. Statistical comparison has been done between all these models. The results demonstrated that ANN model with MBE, RMSE, MPE, R, NSE and t values of -0.0692, 0.5338, 0.2647, 0.9946, 0.9890 and 2.4934 r...

Land surface albedo is a significant parameter for maintaining a balance in surface energy. It is also an important parameter of bare soil surface albedo for developing land surface process models that accurately reflect diurnal variation characteristics and the mechanism behind the solar spectral radiation albedo on bare soil surfaces and for understanding the relationships between climate fac...

pomegranate fruit maturity status is commonly assessed based on external (skin) colour, juice colour and acidity of juice. some researchers have studied the correlation between the parameters of the skin colour and acidity, total soluble solids, citric acid and anthocyanins. this study describes the relationship existing between solar radiation and a colorimetric maturity index in the pomegrana...
