Abstract

We discuss the polarization signals produced in recent realistic 3D simulations of solar magnetoconvection. The Stokes profiles of the Fe I 6301.5, 6302.5, 15648 and 15652 $\mathrm{\AA}$ Zeeman-sensitive spectral lines are synthesised and smeared to simulate the image degradation caused by the Earth's atmosphere and finite telescope resolution. A Principal Component Analysis approach is applied to classify the profiles. We find that the classes of Stokes $V$ profiles as well as their amplitude and area asymmetries are very close to the observations in the network and inter-network regions.To search for other articles by the author(s) go to: http://adsabs.harvard.edu/abstract_service.html
