Aerosol transmittance for clear-sky solar irradiance models: Review and validation of an accurate universal parameterization
Ruiz-Arias, José Antonio
(Elsevier, 2021-04-26)
Accurate modeling of solar radiation under cloudless situations is important to facilitate the development and exploitation of the renewable solar resource worldwide. However, many existing clear-sky solar radiation models ... -
CAELUS: Classification of sky conditions from 1-min time series of global solar irradiance using variability indices and dynamic thresholds
Ruiz-Arias, José Antonio; Gueymard, Christian A. (Elsevier, 2023-08-12)
Precise sky classification as a function of cloudiness is desirable or necessary in a variety of applications. CAELUS, a novel classification algorithm that relies on various thresholds to separate all possible sky conditions ... -
Evaluation of a Database of the Spanish Wind Energy Resources Derived from a Regional Reanalysis
Jiménez-Garrote, Antonio; Santos-Alamillos, Francisco Javier; Sánchez-Hernández, Guadalupe; López-Cuesta, Miguel; Ruiz-Arias, José Antonio; Pozo-Vázquez, David[et al.] (MDPI, 2024-03-22)
An enhanced database (RetroDB) of the Spanish wind energy resources, derived from a high spatial resolution integration with the WRF model, is proposed and evaluated. RetroDB provides hourly capacity factor (CF) values for ... -
Exploring the meteorological potential for planning a high performance European electricity super-grid: Optimal power capacity distribution among countries
Santos-Alamillos, Francisco Javier; Brayshaw, David; Methven, John; Thomaidis, Nikolaos; Ruiz-Arias, José Antonio; Pozo-Vázquez, David[et al.] (IOP, 2017-11-13)
The concept of a European super-grid for electricity presents clear advantages for a reliable and affordable renewable power production (photovoltaics and wind). Based on the mean-variance portfolio optimization analysis, ... -
GISPLIT: High-performance global solar irradiance component-separation model dynamically constrained by 1-min sky conditions
Ruiz-Arias, José Antonio; Gueymard, Christian A. (Elsevier, 2024-01-31)
The separation of global horizontal irradiance (GHI) into its direct and diffuse components is necessary in a variety of applications, most specially in solar energy utilization, where knowledge of direct normal irradiance ... -
Intercomparison of WRF-chem aerosol schemes during a dry Saharan dust outbreak in Southern Iberian Peninsula
Pino-Carmona, Miguel; Ruiz-Arias, José Antonio; Fernández-Carvelo, Sol; Bravo-Aranda, Juan Antonio; Alados-Arboledas, Lucas (Elsevier, 2024-12-15)
The Iberian Peninsula (IP), where this study is conducted, has experienced an increase of the frequency and intensity of Saharan aerosol dust outbreaks over the latest decades, which may have an impact on its regional ... -
Mean-preserving interpolation with splines for solar radiation modeling
Ruiz-Arias, José Antonio (Elsevier, 2022-11-17)
Interpolation is a fundamental process in solar resource assessment that glues consecutive components of the modeling chain. Most interpolation techniques assume that the interpolating function must go through the interpolation ... -
Solar irradiance component separation benchmarking: The critical role of dynamically-constrained sky conditions
Ruiz-Arias, José Antonio; Gueymard, Christian A. (2024-07-01)
The decomposition of global horizontal irradiance into its direct and diffuse components is critical in many applications. To guarantee accurate results in practice, the existing separation techniques need to be validated ... -
SPARTA: Solar parameterization for the radiative transfer of the cloudless atmosphere.
Ruiz-Arias, José Antonio (Elsevier, 2023-10-11)
The high-performance SPARTA broadband clear-sky solar irradiance model is presented. It evaluates global (GHI), diffuse (DIF) and direct normal (DNI) irradiances from atmospheric transmittance functions developed using ... -
Spectral integration of clear-sky atmospheric transmittance: review and worldwide performance
Ruiz-Arias, José Antonio (Elsevier, 2022-03-15)
Broadband atmospheric transmittance is a key component in many broadband clear-sky solar radiation models, whose performance is inevitably bound to the goodness of their atmospheric transmittance parameterizations. A key ...
