The relationships between the four radiant fluxes are analyzed based on a 4 year data
archive of hourly and daily global ultraviolet (IUV), photosynthetically active-PAR (IPAR) …

The study introduces a new regression model developed to estimate the hourly values of
diffuse solar radiation at the surface. The model is based on the clearness index and diffuse …

This study describes correlations between global, diffuse and direct daily solar radiation of
the total spectra and global, diffuse and direct daily solar radiation of the infrared spectra …

Transforming the road public transport to run on renewable energy is vital solution to
achieve carbon neutral and net zero goals. This paper evaluates the potential of using solar …

The city of Rio de Janeiro and others 18 cities compose the Metropolitan Area of Rio de
Janeiro. The main objective of this work is to characterize observationally the diurnal and …

Sugar and ethanol production are key components of Brazil's rural development and energy
strategies, yet in recent years sugar production has been widely criticized for its …

A very important factor in the assessment of solar potential for the installation of photovoltaic
plants is the availability of global irradiation data measurements. Such data must be …

The main goal of this work is to describe the anthropogenic energy flux (QF) in the city of
São Paulo, Brazil. The hourly, monthly, and annual values of the anthropogenic energy flux …

The power output forecasting of the photovoltaic (PV) system is essential before deciding to
install a photovoltaic system in Nakhon Ratchasima, Thailand, due to the uneven power …

The Ångström–Prescott model called M1 together with ten modified versions, all based on
the sunshine duration were adjusted to estimate the daily global and monthly averaged …
