Lower and middle atmosphere and ozone layer responses to solar variation
(Cambridge University Press, 2010-02)
Global warming in the troposphere and the decrease of stratospheric ozone concentration has become a major concern to the scientific community. The increase in greenhouse gases and aerosols concentration is believed to be ...
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 ...
Evolución temporal del índice espectral y el porcentaje de polarización de explosiones solares en banda centimétrica
(1985)
Se analizó la evolución temporal de ocho eventos, con semejante característica espectral, observados simultáneamente en 6,7 y 15,0 GHz en la Estación Radioastronómica de La Habana. Se concluye que no puede hablarse de ...
Atmospheric electric field variations and lower ionosphere disturbance during the total solar eclipse of 2010 July 11
(Elsevier, 2016-11)
In this paper, we study the variations of atmospheric electric field during the total solar eclipse (TSE) of July 11, 2010, at Complejo Astronómico El Leoncito (CASLEO). These variations observed with two identical sensors ...
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 ...
Status of a hybrid three-neutrino interpretation of neutrino data
(Elsevier B.V., 2002-05-13)
We re-analyse the non-standard interaction (NSI) solutions to the solar neutrino problem in the light of the latest solar as well as atmospheric neutrino data. The latter require oscillations (OSC), while the former do ...

Analysis of hourly global, direct and diffuse solar radiations attenuation as a function of optical air mass
(Elsevier B.V., 2014-01-01)
The objective of this work is to verify the attenuation caused by atmospheric constituents through the relationship between global, direct and diffuse solar radiation with respect to optical air mass. The optical air mass ...
