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.

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.

Global Solar Radiation Potential, Part 1: Model Development

Energy Sources, Part B: Economics, Planning, and Policy, 2006
Solar engineers, architects, agriculturists, and hydrologists dealing with many applications of solar energy require a reasonably accurate knowledge about the availability of solar resources at any place. For this purpose, in the past, several empirical correlations have been developed in order to predict the solar radiation around the world.

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.

Assessment of some global solar radiation parameterizations

Journal of Atmospheric and Solar-Terrestrial Physics, 2002
In spite of their practicability, most classical models are not versatile but rather restrictive in their application. Consequently, their applicability for a particular location depends largely on validation against actual measurements. Global solar radiation parameterizations have been evaluated in this study for a lowland and a mountain site. Tested

The Asymmetry of Global Solar Radiation Around Solar Noon

Journal of Applied Meteorology, 1988
Abstract Using approximately 25 years of rehabilitated global solar radiation measurements, an analysis of the asymmetry of global solar radiation around solar noon was performed for three climatic regions of the United states represented by Miami, Florida; Fort Worth, Texas; and Washington, DC.

On the global solar radiation prediction methods

Journal of Renewable and Sustainable Energy, 2016
The availability of reasonably accurate global solar radiation data is vital for the success of any solar project. However, only a few meteorological stations around the world capture these data as a result of the high cost of measuring equipment and the lack of technical capability in calibrating them.

Predicting global solar radiation for South America

Journal of Renewable and Sustainable Energy, 2012
Solar energy is one of the most promising renewable energy sources. The availability of the solar energy potential data is very scarce and often not readily accessible. The main objective of this study was to estimate the monthly average global solar radiation at various locations for South America, by the generalized Iranna-Bapat’s model. Iranna-Bapat’
