The Weimer and IZMEM statistical convection models are driven with a time series of interplanetary magnetic field (IMF) measurements made onboard the Wind spacecraft. The model outputs are used to infer convection velocity at Casey, Antarctica (80.8°S geomagnetic latitude)…
Signatures of the ionospheric cusp in HF digital ionosonde measurements of plasma drift made at the polar cap station Casey, Antarctica (-80.8° geomagnetic latitude) are investigated. Measurements recorded during the campaign interval February 13-17…
The Dopplionogram was developed as a method of displaying Doppler shifts along the frequency axis of ionograms recorded using B-mode soundings of the Dynasonde, an early type of HF digital ionosonde.
Ground-based Fabry-Perot spectrometer observations from the Australian Antarctic stations of Davis and Mawson show an upward wind ~100 m s-1 in the thermosphere at ~240 km altitude on the night of Day of Year 159 in 1997.
The thermopheric oxygen l630 nm emission has been observed using high-resolution Fabry-Perot spectrometers at Mawson (67.6°S, 62.9°E) and Davis (68.6°S, 78.0°E), Antarctica. A new technique, combining the results from the two instruments, is used to derive vector wind fields.
