Sources and characteristics of medium‐scale traveling ionospheric disturbances observed by high‐frequency radars in the North American sector

, 2016
Medium-scale traveling ionospheric disturbances (MSTIDs) are wave-like ionospheric perturbations routinely observed by high-frequency radars. We focus on a class of MSTIDs observed during the winter daytime at high latitudes and midlatitudes.

Simultaneous occurrence of three non-interacting characteristically different ionospheric plasma structures over the geomagnetic low-mid latitude transition region

, 2022
An unusual event of three characteristically different plasma structures on a geomagnetically quiet night (Ap = 4) of 08 July 2018 has been investigated in this paper using an all-sky imager installed at Hanle, Ladakh (32.7°N, 78.9°E; Mlat.

Internal report. Spectral methods for time delay estimation of MSTIDs signal

, 2015
The primary goal of this work is to summarize spectral meth- ods to estimate the time delay variations of the detrended Medium Scale Traveling Ionospheric Disturbances (MSTIDs) signals and pre- liminarily discuss the potential infuence of the Doppler e fects.

Observations of MSTIDs/GWs at the F2 layer heights in the near equatorial region.

Ionospheric vertical sounding observations, using a digital ionosonde (Canadian Advanced Digital Ionosonde(CADI)) , arebeing carried out on a routine basis at Manaus (2,9 0 S; 60,0 0 W; dip latitude 6,4 N, hereafter referred to as MAN), Brazil, locatedbetween the geographic and geomagnetic dip equators, since August 2002, (Fig. 1).
