             abstract = "The present thesis aims at the study of the plasma parameters in 
                         the solar corona, using a flux transport model, force free-field 
                         extrapolations, a model of emission and optimization algorithm. 
                         The physical-model is based on the assumption that the variation 
                         of the irradiance and plasma parameters is due to the evolution of 
                         the solar magnetic field. The goal is to reconstruct electron 
                         density and temperature distributions in the solar corona and the 
                         emission in four different wavelengths during the last two solar 
                         cycles (large scale) and also the emission, electron density and 
                         temperature profiles from Active Region NOAA 11855 (small scale). 
                         The relation between photospheric dynamics, emission, and plasma 
                         parameters in different time scales are reviewed. These 
                         characteristics are important in the Astrophysical and Geophysical 
                         fields, because they can help to understand physical phenomena 
                         such as coronal heating and eruptive events. RESUMO: Esta tese tem 
                         como objetivo principal o estudo dos par{\^a}metros de plasma na 
                         coroa solar, usando um modelo de transporte de fluxo, 
                         extrapola{\c{c}}{\~o}es de campo livre de for{\c{c}}as, um 
                         modelo de emiss{\~a}o e um algoritmo de optimiza{\c{c}}{\~a}o. 
                         O modelo esta baseado na ideia que as varia{\c{c}}{\~o}es da 
                         irradi{\^a}ncia e os par{\^a}metros de plasma est{\~a}o 
                         relacionados com a evolu{\c{c}}{\~a}o do campo magn{\'e}tico 
                         solar. O objetivo {\'e} reconstruir as distribui{\c{c}}{\~o}es 
                         de densidade e temperatura na coroa solar e a emiss{\~a}o em 
                         quatro comprimentos de onda diferentes durante os dois 
                         {\'u}ltimos ciclos solares e tamb{\'e}m a emiss{\~a}o, perfis 
                         densidade eletr{\^o}nica e temperatura usando a regi{\~a}o ativa 
                         NOAA 11855. A rela{\c{c}}{\~a}o entre a din{\^a}mica, 
                         emiss{\~a}o e par{\^a}metros de plasma em diferentes escalas de 
                         tempo s{\~a}o revisadas. Estas caracter{\'{\i}}sticas s{\~a}o 
                         importantes em astrof{\'{\i}}sica e geof{\'{\i}}sica, porque 
                         podem ajudar a entender fen{\^o}menos f{\'{\i}}sicos como o 
                         aquecimento coronal e eventos eruptivos.",
