Task 9 - Solar Radiation and Pyranometry Studies
Improved Measurement of Solar Irradiance by Means of Detailed Pyranometer Characterisation
April 1996 - PDF 7.89MB
By: D.I. Wardle, et al., Atmospheric Environment Service, Canada
The focus of the work is on determining the effects of factors other than irradiance on the signals from pyranometers, which is the meaning of characterisation in the context of pyranometery. Results from eleven laboratories on nearly thirty pyranometers of seven types have been examined.

Using Pyranometers in Tests of Solar Energy Convertors: Step-by-Step Instructions
November 1995 - PDF 8.02MB
By: L.B.J. McArthur, et al., Atmospheric Environment Service, Canada
This report offers a step-by-step guide to the measurement of global solar radiation for the purpose of determining the efficiency of flat plate solar collectors. Comprehensive instructions are provided for each stage of the procedure, including where to obtain instrument responsivities and how to install and operate pyranometers and their data acquisition systems. It is assumed the reader has some technical expertise in collector installation and operations, but not necessarily familiar with the measurement of solar radiation.

IEA Comparisons of Global Solar Radiation Reference Radiometers
March 1995 - PDF 1.09MB
By: L. Liedquist, et al., Swedish National Testing and Research Institute
In solar energy research the ability to accurately measure the incoming solar irradiance level is important. This report presents the findings from two studies which compared three reference instruments to verify the 1% uncertainty and also to assess the state-of-the-art.

Techniques for Supplementing Solar Radiation Network Data - Volume 1: Report
September 1992 - PDF 7.43MB
By: Antoine Zelanka, Gerhard Czeplak, Vito D'Agostino, Weine Josefsson, Eugene Maxwell, Richard Perez
Solar radiation data are required for resource assessment, simulation model development and validation, system design and evaluation, collector testing, and other activities in the field of solar energy research and application. A complex computer model may be useless if accurate input data from a near-by measuring station are not available. On the other hand, the density of radiometric stations is limited for economical reasons. Thus, there is a need for spatially continuous mapping of solar radiation.

Techniques for Supplementing Solar Radiation Network Data - Volume 2: Theory
September 1992 - PDF 2.29MB
By: Antoine Zelanka, Gerhard Czeplak, Vito D'Agostino, Weine Josefsson, Eugene Maxwell, Richard Perez
The procedure of estimating the values of physical properties at unsampled sites within areas covered by existing observation networks is call interpolation, while outside the areas it it call extrapolation. The value of a variable between data points can be interpolated only by fitting some plausible model of variation to the values at the data points and then calculating the value at the requested location.

Validation of Models for Estimating Solar Radiation on Horizontal Surfaces - Vol. 1: Report
June 1988 - PDF 2.4MB
By: J.A. Davies, et al., McMaster University, Canada
This report documents the evaluation of the performance of numerical models that provide estimates of solar irradiance on horizontal surfaces. This report is significant because it used 15 data sets representing a range of solar climates over a number of years. Countries documented are Australia, Canada, Germany, Switzerland, the Netherlands, the U.K. and the USA.
