RT Journal Article T1 Field Quality Control of Spectral Solar Irradiance Measurements by Comparison with Broadband Measurements A1 Marzo, Aitor A1 Ballestrín, Jesús A1 Alonso Montesinos, Joaquín A1 Ferrada, Pablo A1 Polo, Jesús A1 López Rodríguez, Gabriel A1 Barbero, Javier AB Measurement of solar spectral irradiance is required in an increasingly wide variety oftechnical applications, such as atmospheric studies, health, and solar energy, among others. The solarspectral irradiance at ground level has a strong dependence on many atmospheric parameters. Inaddition, spectroradiometer optics and detectors have high sensitivity. Because of this, it is necessaryto compare with a reference instrumentation or light source to verify the quality of measurements. Asimple and realistic test for validating solar spectral irradiance measurements is presented in thisstudy. This methodology is applicable for a specific spectral range inside the broadband range from280 to 4000 nm under cloudless sky conditions. The method compares solar spectral irradiancemeasurements with both predictions of clear-sky solar spectral irradiance and measurements ofbroadband instruments such as pyrheliometers. For the spectral estimation, a free atmospherictransmittance simulation code with the air mass calculation as the mean parameter was used. Thespectral direct normal irradiance (Gbl) measurements of two different spectroradiometers were testedat Plataforma Solar de Almería, Spain. The results are presented in this article. Although only Gblmeasurements were considered in this study, the same methodology can be applied to the other solarirradiance components PB MDPI SN 2071-1050 (electrónico) YR 2021 FD 2021 LK http://hdl.handle.net/10272/20262 UL http://hdl.handle.net/10272/20262 LA eng NO Marzo, A., Ballestrín, J., Alonso-Montesinos, J., Ferrada, P., Polo, J., López, G., & Barbero, J.
