Abstract

Exposing the polarization signatures of the solar chromosphere requires studying its temporal variations, which is rarely done when modelling and interpreting scattering and Hanle signals. The present contribution sketches the scientific problem of solar polarization diagnosis from the point of view of the temporal dimension, remarking some key aspects for solving it. Our time-dependent calculations expose the need of considering dynamics explicitly when modelling and observing scattering polarization in order to achieve effective diagnosis techniques as well as a deeper knowledge of the second solar spectrum.
