A study of traveling ionospheric disturbances and their associated scintillation behaviors at South Pole

TIDs are the large scale electron density perturbations that travel in the ionosphere and can be tracked by number of instruments, like incoherent scatter radar, ionosondes, HF Dopler system etc. They are believed to be the signature of atmospheric gravity wave in the high latitude ionosphere, which are generated due to geomagnetic activities [1].
