Medium Scale Traveling Ionospheric Disturbances (MSTIDs) are quasi-periodic variations in the F region ionospheric electron density. MSTIDs can be associated with atmospheric gravity waves (AGWs) and provide critical information for understanding neutral atmosphere-ionospheric coupling. Previous SuperDARN studies of MSTIDs have used the Multiple Signal Classification (MUSIC) algorithm to determine the horizontal wavelength, propagation direction, propagation velocity, and period of MSTIDs moving through the SuperDARN radar field of view. However, error bars for the MUSIC-derived MSTID parameters still need to be implemented. In this presentation, we revisit the MUSIC algorithm and present techniques for incorporating error bars on these measurements.
