Here, we present the results of our investigation on quiet photospheric fields. We study the features of intensity and velocity solar fields as derived from observations of photospheric lines, obtained at the French-Italian THEMIS telescope (Observatorio del Teide, Tenerife) using the Italian Panoramic Monochromator (IPM). In detail, the vertical dynamics is investigated using monochromatic observations at three spectral lines (C I 538.0, Fe I 537.9, and Fe I 557.6), as representative of three atmospheric heights in the overshooting photosphere. Moreover, granulation properties and horizontal flows are also studied using broad band images.

Abstract

Here, we present the results of our investigation on quiet photospheric fields. We study the features of intensity and velocity solar fields as derived from observations of photospheric lines, obtained at the French-Italian THEMIS telescope (Observatorio del Teide, Tenerife) using the Italian Panoramic Monochromator (IPM). In detail, the vertical dynamics is investigated using monochromatic observations at three spectral lines (C I 538.0, Fe I 537.9, and Fe I 557.6), as representative of three atmospheric heights in the overshooting photosphere. Moreover, granulation properties and horizontal flows are also studied using broad band images.
