In the realm of solar forecasting, it is common to use a clear sky model output to deseasonalise the solar irradiance time series needed to build the forecasting models. However, most of these clear sky models require the ...

This paper presents an analysis of the frequency of the sky conditions in Botucatu. The classification of sky conditions was made based on the clearness index (K T), calculated from a database with 10 years of measured ...

Three simple clear-sky models using easily available mean average atmospheric data are evaluated against hourly ground data for five sites in Uruguay. The ESRA model, based on a mean daily cycle Linke Turbidity calculated ...

While the use of satellite weather files is a possibility in regions without terrestrial stations, it is necessary to consider their impact on daylight simulations. This paper aims to verify the variability of dynamic ...

This work describes a new algorithm to characterize sky condition in intervals of 5min using four categories of sun exposition: apparent sun with cloud reflection effects; apparent sun without cloud effects; sun partially ...

The Argentinean Northwest (ANW) is a high altitude region located alongside Los Andes Mountains. The ANW is also one of the most insolated regions in the world due to its altitude and particular climate. However, the ...

Glare is considered one of the most important variables to reach visual comfort and visual quality. It represents one of the fundamental barriers for an effective use of daylighting in buildings. One of the best performing ...
