Statistical GNSS-RO measurements of phase and amplitude scintillation are analyzed at the
mid-latitudes in the local summer for a 100 km altitude. These conditions are known to …

Thermospheric neutral winds (TNWs) refer to the neutral gases in the thermosphere
circulating as tides, which play a crucial role in the dynamics of the thermosphere …

We have investigated equinoctial asymmetry of scintillation occurrence and zonal
irregularity drift velocity observed with closely-spaced GPS receivers at Kototabang (0.20° S …

Ionospheric scintillations due to plasma irregularities can severely affect the modern
dynamic and technological systems whose operations rely on satellite-based navigation …

Studies on counter-electrojet currents (CEJ) using ground data revealed that this current
could occur simultaneously among locations that are less than 30° longitude apart. In our …

This paper presents a multi-instrument observational analysis of the equatorial plasma
bubbles (EPBs) variation over the American sector during a geomagnetically quiet time …

The temperature and wind in the middle and upper atmosphere can be obtained by
recording the Doppler shift and broadening of the airglow emission, which is reflected by the …

By using fast ionogram observations, we report the first simultaneous observations of
ascending ion layers at equatorial and low latitudes. The ionosonde measurements at …

A digital ionosonde of the type known as Canadian Advanced Digital Ionosonde (CADI) is
operational at Jatai (17.2 o S, 51.9 o W), Brazil. This ionospheric sounding station is located …

The present study aims to investigate the behaviour of equatorial plasma bubbles (EPBs)
during quiet days in Southeast Asia (SEA). The behaviour of EPB was determined by …
