The difference between the observed frequencies of the l = 0 modes (Broomhall et al. 2009; Davies et al. 2014), and the frequencies calculated based on the SSM-K1 (orange diamonds), SSM-MLT (blue circles), and the solar model from Jørgensen & Weiss (2019), with inclusion of turbulent pressure and patched 3D atmosphere (green crosses) is shown. For the solar model from Jørgensen & Weiss (2019), the structural surface effect is corrected, and the difference between observed and calculated frequencies can be explained by remaining modal effects.
