Plasma Diagnostics for the Solar Atmosphere
Abstract
Superb observations are now being obtained with the ESA/NASA Solar Heliospheric Observatory (SOHO). In these lectures, I discuss the spectroscopic diagnostic techniques used to analyse ultraviolet and X-ray spectra. Intensities of the spectral emission lines can be used to determine the electron density and temperature structure, element abundances and dynamic nature of different features in the solar transition region and corona. To ensure that these techniques are accurate it is necessary to model all the important atomic processes with the best available atomic data calculations. I discuss the analysis of SOHO spectra and look towards other astrophysical UV and X-ray observations.
