abstract = "Traveling ionospheric disturbances (T!Ds) are wave-like
disturbances in ionospheric plasma density. They are often
observed during both quiet (Medium scale TID) and geomagnetic
disturbed (Large Scale TID) conditions. Their amplitudes can be up
to I 0% of the background plasma density and their presence
provides a challenge to existing radio wave propagation theories.
In this study, we investigate how TIDs generation mechanism and
propagation vary with different plasma background densities during
various geophysical conditions. The transequatorial coupling
ofTIDs north and south hemispheres are also investigated with
respect to attenuation and propagation characteristics. We show
that TID properties during transequatoriaxl events may be
substantially affected by background neutral wind perturbation
(owning to disturbance dynamo affects), vertical and horizontal
velocity which are seasonal dependent. Our study observations
occurred during both quiet and geomagnetic disturbed periods using
multiple ground and space borne instruments, suc.h as:
Magnetometers, GNSS receivers as well as the DMSP and SWARM
satellite missions in low Earth orbit.",
