Improving the Ni I atomic model for solar and stellar atmospheric models
(IOP Publishing, 2013-05-10)
Neutral nickel (Ni I) is abundant in the solar atmosphere and is one of the important elements that contribute to the emission and absorption of radiation in the spectral range between 1900 and 3900 Å. Previously, the Solar ...

Diurnal evolution of the hourly diffuse solar radiation incident on tilted surfaces in Southeast of Brazil
(2013)
Evaluation has been made on the monthly and annual average diurnal evolution of the hourly diffuse radiation as well as its radiometric fractions on surfaces inclined at 12.85, 22.85 and 32.85° to face North, in climate ...
Estudo da atividade solar no passado em função da radiação cósmica
(Universidade Federal de Santa MariaCentro de Ciências Naturais e Exatas, 2014-03-20)
The study about cosmic radiation arriving the Earth represents an important register of its variations, as the physical phenomena who cause these variations. In the solar system the variation is strongly modulated by the ...
Radiative constraints on the hydrological cycle in an idealized radiative-convective equilibrium model
(American Meteorological Society, 2009-01)
The radiative constraints on the partitioning of the surface energy budget and, hence, on the strength of the hydrological cycle are analyzed in an idealized one-dimensional radiative–convective equilibrium model formulated ...
