Atmospheric electric field … measurements from the Concordia station on the Antarctic Plateau are … compared with those from Vostok (560 km away) for the period of overlap … (2009–11) and to Carnegie (1915–29) and extended Vostok (2006–11) measurements.
Reference IUGG-2058, Symposium M03 Weather and the Global Atmospheric Electric Circuit. Atmospheric electric field measurements from Concordia station on the Antarctic Plateau are compared with those from Vostok (560 km away) for the period of overlap (2009-2011) and to earlier Vostok (2006-2009)…
A new all-sky imaging Fabry-Perot spectrometer … has been installed at Mawson station (67360 S, 62520 E), Antarctica. This instrument is capable of recording independent … spectra from many tens of locations across the sky simultaneously. Useful operation began in March 2007…
Superposed epoch analysis (SEA) was used to examine ionospheric drift velocities measured by a digital … ionosonde located at the mid-latitude station Bundoora (145.11E, 37.71S geographic), near Melbourne. The control times for the SEA were the times of cloud-to-ground (CG)…
Mid-latitude Digisonde Doppler velocities, auroral electrojet (AE) indices and cloud-to-ground (CG) lightning strokes during August 2003–2004 were used to study the perturbations in the F-region … vertical drift associated with terrestrial thunderstorms. A superposed epoch analysis (SEA)…
AB: We investigate the storm-time E-region backscatter observed by the … Tasman International Geospace Environment Radar (TIGER) HF radars. In … the afternoon sector during the negative geomagnetic storm phase…

[1] Using Rayleigh lidar and Mesosphere-Stratosphere- … Troposphere radar at Davis Antarctica (68.6S) during the … 2005–2006 austral summer, we obtained the first Southern … Hemisphere common-volume measurements of Polar … Mesospheric Clouds (PMC) and Polar Mesosphere … Summer Echoes (PMSE).
Akasofu’s solar wind " parameter describes the … coupling of solar wind energy to the magnetosphere and … ionosphere. Analysis of fluctuations in " using model independent … scaling techniques including the peaks of probability … density functions (PDFs)…
We present wind and temperature profiles at Dome C measured … by balloon born sonds during the polar summer. Data from 197 … flights have been processed for 4 campaigns between 2000 and 2004. We show the exceptionnal wind conditions at Dome C, Average ground … wind speed is 3.6 m/s.
A review is presented of passive coherent and incoherent radar observations of … ultra-low-frequency (ULF) waves. Passive radars primarily observe the ionospheric … signatures of the shear Alfven field line resonance (FLR). Recent results … include:
Antarctic vegetation is exposed to elevated levels of UV-B … radiation (UVBR) as a result of ozone depletion. Three species of … co-occurring Antarctic bryophytes, Bryum pseudotriquetrum…
Induction magnetometer data recorded at three closely spaced sites (110km) in Antarctica (mlat -75°) have been examined for ionospheric signatures of the outer magnetosphere and cusp/cleft regions. Cross-phase analysis of the 1–10 mHz band…
The diving behaviour of Adelie penguins Pygoscelis adeliae was studied with time-depth recorders at Dumont DUrville, Antarctica, during the breeding seasons in 1995/1996 and 1996/1997. We studied penguins foraging at all breeding stages, in various sea-ice conditions.
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…
