A global classification of solar radiation

Solar Energy, 1970
Abstract A series of indices has been constructed in an attempt to regionalize the annual march of solar radiation on a global scale. Over one thousand sampling points were used in order to derive the spatial distribution of the 12-month radiation curve.

Global solar radiation climate of Libya

Energy Conversion and Management, 1992
Abstract This paper presents the general features of the global solar radiation measured by 15 meteorological stations spread over Libya during the 5-yr period, 1981–1986. A number of methods for correlating monthly average daily global radiation with recorded sunshine duration have been attempted.

Analysis of the Global Solar Radiation and Solar Energy in Ruse, Bulgaria

2021 17th Conference on Electrical Machines, Drives and Power Systems (ELMA), 2021
In the present study is performed a harmonic analysis of the global solar radiation for the region of Ruse, Bulgaria. The study is based on radiation data obtained from a meteorological station in the campus of the University of Ruse. Initially, basic statistical analysis was performed.

Global solar radiation estimation in Algeria

Energy Conversion and Management, 2001
In this paper, two models for estimating monthly average daily global radiation on a horizontal surface have been applied to four different locations. The first one is an empirical model, originally formulated by Barbaro et al. (Solar Energy 20 (1978) 431). Some modifications have been suggested.

Exergy of solar radiation: global scale

Ecological Modelling, 2003
A new concept regarding the exergy of solar radiation [Ecol. Model. 145 (1991) 101] is applied to the analysis of satellite data describing the seasonal (monthly) dynamics of four components of the global radiation balance: incoming and outgoing short- and long-wave solar radiation.

A correlation for estimation of global solar radiation

Energy, 1987
Abstract We present a simple Angstrom-type correlation for estimating the monthly average daily horizontal global radiation. We have developed this correlation using the bright sunshine and global radiation data of 48 locations around the world, with varied meteorological conditions and a wide distribution of geographical locations.

Estimation of the global solar radiation in Greece

Solar & Wind Technology, 1986
Abstract In this paper a method to estimate the global solar radiation in Greece is proposed. Measurements of the global solar radiation available by seven meteorological stations in Greece are used to obtain the regional regression coefficients of the Page formula.

Estimation of global solar radiation in Benin

Renewable Energy, 1992
Abstract Following Frere and Rietveld's model, correlation constants a and b were determined for many stations in Benin using: • - a graphical relationship between the average annual relative sunshine SS / SS ′o and the constants (Frere's model).

Data compression technique for modeling of global solar radiation

2011 IEEE International Conference on Control System, Computing and Engineering, 2011
This paper studies the use of wavelet transform and curve fitting methods for solar radiation compression and prediction-based modeling. Symlet 6 and Meyer wavelets will be utilized for analyzing the transient nature of solar radiation. The measured solar radiation data will be decomposed up to level 4.
