Monthly averaged-hourly solar diffuse radiation model for the UK

Abstract

Monthly-averaged daily global irradiation data are now easily available from NASA website. Using established models it is then possible to decompose the daily-to averaged-hourly global irradiation. The missing link so far has been hourly averaged diffuse irradiation. In this article data was pooled from 10 UK locations to obtain a regression model to complete the above missing link. It was presently shown that the averaged-data regressions are distinctly different from previously available hour-by-hour regressions.

Empirical Models for the Estimation of Solar Sky-Diffuse Radiation. A Review and Experimental Analysis

“…This information includes long-term estimated values of meteorological measures and surface solar energy fluxes provided by satellite systems. These data meet the needs of renewable energy community and it has been proven they are accurate enough to provide consistent solar and meteorological data for locations where records are scarce or non-existent [59].…”

Development of solar isodose lines: Mercatorian and spatial guides for mapping solar installation areas

“…Generally, the direct linear relationship between the normalized SPP and the clearness index dominates the solar power potential (SPP) model. Essentially, the clearness index signifies the intensity or magnitude of the cloud within the study area [1] , [2] , [3] , [4] , [5] , [6] , [7] . The input parameters of the SPP model include temperature, altitude and sunshine hours, longitude, clearness index, wind speed and extraterrestrial radiation [8] , [9] , [10] , [11] , [12] , [13] , [14] , [15] , [16] , [17] .…”

Modeling of the hourly horizontal solar diffuse radiation in Sanliurfa, Turkey

“…In this traditional analysis, they did the validation study on the basis of absolute relative error and mean absolute error squared without considering the characteristic of linearity and modelling. Muneer et al [29] proposed 14 diffuse radiation models based on the relationship between diffuse radiation rate and clarity index taken from the NASA measurement data for 14 locations between 13° and 59° latitudes. Kotti et al [30] compared four diffusive radiation correction models to eliminate diffuse radiation calculation errors affecting direct radiation calculation.…”
