Analytical expressions for estimating sky diffuse irradiance and illuminance on tilted planes for the CIE standard general skies
Torres Escribano, José Luis
; García Ruiz, Ignacio (Elsevier, 2021)
Artículo / Artikulua
This work proposes a set of analytical expressions for the calculation of the relationship between sky diffuse illuminance on a tilted plane and horizontal plane corresponding to the 15 ISO/CIE standard sky types. Given ... -
Daylight modeling in complex environments considering the angular distribution of sky luminance
García Ruiz, Ignacio (2021)
Tesis doctoral / Doktoretza tesia
The general objective of this thesis is the modeling of daylight in complex environments, such as cities. This requires precise knowledge, both geometric and photometric, of the environment and of the sources of radiation ... -
Diffuse irradiance on tilted planes in urban environments: evaluation of models modified with sky and circumsolar view factors
García Ruiz, Ignacio ; Blas Corral, María Ángeles de ; Hernández Salueña, Begoña ; Sáenz Gamasa, Carlos ; Torres Escribano, José Luis (Elsevier, 2021)
Artículo / Artikulua 
Numerous studies have analyzed existing irradiance models for estimating sky diffuse irradiance on tilted planes. However, few have evaluated the suitability of these models for estimating irradiance in obstructed environments, ... -
Evaluación multitemporal de métodos de corrección topográfica mediante el uso de imágenes sintéticas multiespectrales
Sola Torralba, Ion ; Álvarez-Mozos, Jesús ; González de Audícana Amenábar, María ; Torres Escribano, José Luis (Asociación Española de Teledetección, 2014)
Artículo / Artikulua
En este trabajo se presentan los resultados de la evaluación multitemporal de varios métodos de corrección topográfica (TOC), cuya bondad se determina de forma cuantitativa mediante el uso de imágenes sintéticas multiespectrales ... -
Evaluation of two procedures for selecting the CIE standard sky type using high dynamic range images
García Ruiz, Ignacio ; Blas Corral, María Ángeles de ; Torres Escribano, José Luis ; Hernández Salueña, Begoña ; Sáenz Gamasa, Carlos ; Ormazábal Pagola, Mikel (International Solar Energy Society, 2019)
Contribución a congreso / Biltzarrerako ekarpena
The characterization of sky conditions according to the CIE Standard General Sky classification requires knowledge of diffuse luminance angular distribution in the sky vault. This variable is usually measured by sky scanners. ... -
Multitemporal evaluation of topographic correction algorithms using synthetic images
Sola Torralba, Ion ; Álvarez-Mozos, Jesús ; González de Audícana Amenábar, María ; Torres Escribano, José Luis (SPIE, 2012)
Contribución a congreso / Biltzarrerako ekarpena
Land cover classification and quantitative analysis of multispectral data in mountainous regions is considerably hampered by the influence of topography on the spectral response pattern. In the last years, different ... -
Proposal and evaluation of typical illuminance year (TIY) generation procedures from illuminance or irradiance data for daylight assessment in the long term
García Ruiz, Ignacio ; Blas Corral, María Ángeles de ; Torres Escribano, José Luis (ElsevierInternational Solar Energy Society, 2020)
Artículo / Artikulua
When assessing the long-term daylight availability or the performance of natural lighting systems in a given location, it is necessary to have representative data of local daylight conditions. The use of a daylight test ... -
Radiación solar: principios, evaluación y aprovechamientos
Torres Escribano, José Luis (Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2009)
Otros / Bestelakoak
En esta lección se tratará la radiación solar desde un punto de vista energético. En concreto, tras una obligada introducción en la que se establecerá su carácter, se pondrá de manifiesto su importancia para la humanidad ... -
The sky characterization according to the CIE Standard General Sky: comparative analysis of three classification methods
García Ruiz, Ignacio ; Blas Corral, María Ángeles de ; Torres Escribano, José Luis (Elsevier, 2020)
Artículo / Artikulua
Since the publication of the standard sky luminance distributions (SSLD) that was consolidated in the ISO 15469:2004(E)/CIE S 011/E:2003, numerous procedures have emerged for the characterization of the sky condition ... -
Synthetic images for evaluating topographic correction algorithm
Sola Torralba, Ion ; González de Audícana Amenábar, María ; Álvarez-Mozos, Jesús ; Torres Escribano, José Luis (IEEE, 2013)
Artículo / Artikulua
In the last years, many topographic correction (TOC) methods have been proposed to correct the illumination differences between the areas observed by optical remote sensors. Although the available number of TOC methods is ...
