In the first paper the magnetic field vector of a plage region is inferred using STiC, a spectro-polarimetric inversion code, which is achieved after applying several methods to improve the signal to noise ratio. In all three cases I utilize high-resolution spectral and spectro-polarimetric data from the Swedish 1-m Solar Telescope (SST) in order to constrain the physical parameters of these regions and to create high resolution reference profiles of the quiet regions. Additionally, I study the quiet solar atmosphere for calibration purposes. This thesis focuses on plage and peacock-jets, two types of chromospheric features. Observations of the active features found in the chromosphere such as plage, fibrils, and jets, are therefore more difficult to interpret than emission from active features in the photosphere. On top of that most of its observable radiation is formed in conditions far from thermodynamic equilibrium, and thus only partially sensitive to local plasma conditions. However, studying this layer is not straightforward, as it is largely transparent in optical wavelengths. It acts as an important interface between the photosphere below it and the hot corona above. The chromosphere is a complex and dynamic layer of the solar atmosphere, largely dominated by the local magnetic field configuration. ![]() The data pipeline of the forthcoming CHROMIS instrument.
