Abstract

High spatial resolution observations recorded with the Swedish Vacuum Solar Telescope are used to study the atmospheric structure of the penumbra of sunspots. Spectra in the wing of the Ca II K line are inverted to derive the temperature distribution of fine-scale structures in the penumbra. Weak line blends in the Ca II K wing probe the Evershed effect at different heights in the atmosphere.
