Research Abstract

We have analyzed E- and F-region field-aligned irregularities (FAIs) observed by a VHF backscatter radar with an operating frequency of 30.8 MHz in Indonesia and revealed statistically local time, seasonal, and solar activity variations of the FAI occurrence rates. Propagation characteristics and drift velocities of the FAIs are also investigated. Especially, we have studied the post-midnight F-region FAIs and suggested that the post-midnight FAIs are likely associated with either plasma bubbles or medium-scale traveling ionospheric disturbances (MSTIDs).
