CIE 241:2020 Recommended Reference Solar Spectra for Industrial Application

Abstract

This document provides CIE recommended reference solar spectra for industrial applications. It contains a large selection of simulation benchmarks for total, direct and diffuse components of solar spectra under various atmospheric conditions and solar geometries (defined by the air mass). For this purpose a freely available solar spectral irradiance model has been used to generate tables and figures of solar spectral irradiance under a number of different atmospheric conditions, in the form of explicit meteorological input parameters. The data as provided in this document are to a large extent comparable to those in CIE 085-1989, but they are presented with a higher spectral sampling. The respective solar spectra are the basis for national and international standard reference spectra for various applications. They have been extensively validated against measured spectra. Keywords: daylight, irradiance, simulated solar radiation, solar radiation

“…Array spectroradiometers are also adopted in studies about air quality, photochemistry and atmospheric composition [12][13][14][15][16][17][18][19][20][21], by taking advantage of the spectral signature of some light-absorbing atmospheric compounds; phototherapy and medical dosimetry [22,23], in which the observation of the radiation spectrum is essential for assessing wavelengthdependent biological effects; measurement of the Earth's surface reflectance, e.g., to identify snow impurities [24]; and the monitoring of water quality and ecosystems [25][26][27]. Finally, array systems are not only useful in research but may also be introduced in industrial applications where reference solar spectra are required [28] or where spectroscopy-based techniques are employed for process control [29]. Additional examples are provided in Section S1.…”
