【 摘 要 】

Simultaneous measurements at different wavelengths offer the prospect of studying the sensitivity of helioseismic inferences to the choice of observing height both in quiet-Sun and magnetically active regions. In this context, we use observations from space-borne measurements from the Solar Dynamics Observatory and ground-based Global Oscillation Network Group to analyze high-degree acoustic mode parameters and sub-surface flows obtained with different observables. We also quantify differences and interpret results in the framework of the formation height in solar atmosphere.
