Abstract
Understanding the dynamic behavior of spicules, e.g., in terms of magnetohydrodynamic (MHD) wave mode(s), is\ud key to unveiling their role in energy and mass transfer from the photosphere to corona. The transverse, torsional,\ud and field-aligned motions of spicules have previously been observed in imaging spectroscopy and analyzed\ud separately for embedded wave-mode identification. Similarities in the Doppler signatures of spicular structures for\ud both kink and torsional Alfvén wave modes have led to the misinterpretation of the dominant wave mode in these\ud structures and is a subject of debate. Here, we aim to combine line- of-sight (LOS) and plane-of-sk...
