Description

We analyze high-resolution spectropolarimetric observations from TuMag/SUNRISE III in the Fe I 5250.2 Å and Mg I b2 5173 Å lines to investigate how sunspot properties change from the photosphere to the low chromosphere, a transition layer characterized by key changes in the thermal, dynamic, and magnetic structure of the solar atmosphere.
We perform a comparative analysis using both spectral lines to study how the velocity and magnetic field structures vary across this interface in sunspot environments, with particular emphasis on the penumbral region.
