 Abstract: Irregularities in ionospheric plasma distribution can result in severe scintillation to radio frequencies utilized for satellite navigation. In the low latitudes, these irregularities can include Equatorial plasma bubbles (EPBs) and Travelling Ionospheric Disturbances (TIDs). High frequency in-situ measurements of ionospheric plasma aboard spacecraft in Low Earth Orbit (LEO) are a direct measurement of irregularities in plasma density, and are valuable for resolving EPB and TID occurrences, variability, and relation to other ionospheric parameters drivers, such as vertical plasma drift. In this study, we utilize observations taken between 2017 – 2020 by the Advanced Ionospheric Probe (AIP) carried aboard the FORMOSAT-5 satellite to examine the variability of low latitude ionospheric irregularities and vertical ion drift during this time. AIP provides in-situ measurements of ion density and vertical ion drift in the low to mid-latitude ionosphere at approximately 720 km altitude with local times between 22:00 – 23:00 local time. Our global scale results resolve distinct and inter-annually recurrent seasonal patterns in the distribution of ionospheric irregularities and vertical plasma drift during this time. Although some interannual variability in irregularities is observed, the spatial and interannual variation of the co-located vertical ion drifts were much more consistent during the years examined, indicating that the driver for the observed interannual variability in irregularities cannot be attributed to the wind dynamo driven vertical ion drift.
