Abstract
We present a new inversion methodology that adapts the inversion grid in both radius and co-latitude to the data set and solves the inversion problem through an iterative procedure. This method was tested on state-of-the-art global mode frequency splittings to assess the solar interior rotation rate and its temporal variation. We also explore the influence of different data sets on the interpretation of the dynamics of the solar interior, particularly the spatial extend of the torsional oscillations.
