The Ca IR triplet lines are a good candidate for observing chromospheric magnetic fields. Simulations of the lines in the high-beta regime, spectropolarimetric observations and inversions of observations give insight to their usabilitysuitability in observing QS magnetic fields and dynamics. Propagating waves are clearly visible in the simulations, both in Stokes V and I. Observed line profiles are found to be more complicated, though they do indicate the presence of waves. We present both simulated and observed profiles and analyze the ability of the NLTE inversion algorithm to retrieve the underlying physics in the solar atmosphere.
