Resumo: 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.
