TL;DR: The first campaign of the Polar Patrol Balloon (1st-PPB) experiment (1992-1993) was carried out at Syowa Station in Antarctica during 1990-1991 and 1992-1993 as discussed by the authors.
Journal ArticleDOI
Simultaneous ground-satellite optical observations of postnoon shock aurora in the Southern Hemisphere
TL;DR: In this paper, a transient post-noon shock aurora was observed simultaneously with the FUV imager onboard the IMAGE satellite and the all-sky imager (ASI) at the South Pole Station (−74.3° magnetic latitude (MLAT), ∼15 magnetic local time).
Journal ArticleDOI
Auroral radio emission and absorption of medium frequency radio waves observed in Iceland
Yuka Sato,Takayuki Ono,Masahide Iizima,Atsushi Kumamoto,Natsuo Sato,Akira Kadokura,Hiroshi Miyaoka +6 more
TL;DR: In this article, an Auroral Radio Spectrograph (ARS) system was installed at Husafell station in Iceland (invariant latitude: 65.3°) to study the generation and propagation processes of MF auroral radio emissions (referred to as auroral roar and MF burst) in the polar ionosphere.
Journal ArticleDOI

TL;DR: In this article, a general-purpose Monte Carlo particle transport simulation code was used to quantitatively evaluate the ionization in the middle atmosphere during the observed auroral break-up.
Journal ArticleDOI
Unmanned magnetometer network observation in the 44th Japanese Antarctic Research Expedition: Initial results and an event study on auroral substorm evolution
TL;DR: In the 44th Japanese Antarctic Research Expedition (JARE-44) during 2003 to 2004, four unmanned magnetometers were deployed in Antarctica to establish a observation network for studying ionospheric and magnetospheric phenomena as discussed by the authors.
