Field Quality Control of Spectral Solar Irradiance Measurements by Comparison with Broadband Measurements

Measurement of solar spectral irradiance is required in an increasingly wide variety technical applications, such as atmospheric studies, health, and energy, among others. The at ground level has a strong dependence on many parameters. In addition, spectroradiometer optics detectors have high sensitivity. Because this, it necessary to compare with reference instrumentation or light source verify the quality measurements. A simple realistic test for validating measurements presented this study. This methodology applicable specific range inside broadband from 280 4000 nm under cloudless sky conditions. method compares both predictions clear-sky instruments pyrheliometers. For estimation, free transmittance simulation code air mass calculation mean parameter was used. direct normal (Gbλ) two different spectroradiometers were tested Plataforma Solar de Almería, Spain. results are article. Although only Gbλ considered study, same can be applied other components.
