Description:

We investigate the ionospheric variability due to traveling ionospheric disturbances (TIDs) over Wallops Island, VA, using Dynasonde-derived measurements of ionospheric tilts and vertical Doppler speedbetween May 2013 and August 2016, covering the bottomside ionospheric Flayer. The mean power spectral density is determined separately for each month for both ionospheric tilts and for the Doppler speed, with a 2 km resolution in a broad altitude range. This is accomplished using a spectral analysis technique based onthe Lomb-Scargle and Welch methods, with an added ﬁltering criterion. The analysis is performed separately for the daytime and nighttime data. By investigating the seasonal variability of the power spectral density integral, a semiannual variation is highlighted in the overall level of daytime TID activity, with increasedactivity during summer and winter seasons in the northern hemisphere. This result provides a more complete picture than other recent publications that only highlighted a winter peak in the same geographical sector.
