Journal ArticleDOI
Ionospheric disturbances detected by GPS total electron content observation after the 2011 off the Pacific coast of Tohoku Earthquake
Takuya Tsugawa,Akinori Saito,Yuichi Otsuka,Michi Nishioka,Takashi Maruyama,Hisao Kato,Tsutomu Nagatsuma,Ken T. Murata +7 more
TL;DR: In this paper, the authors focused on the concentric wave propagation characteristics of the 2011 Tohoku earthquake and revealed the details of ionospheric disturbances by high-resolution GPS total electron content observation in Japan.
Journal ArticleDOI
On post‐midnight field‐aligned irregularities observed with a 30.8‐MHz radar at a low latitude: Comparison withF‐layer altitude near the geomagnetic equator
Michi Nishioka,Yuichi Otsuka,Kazuo Shiokawa,Takuya Tsugawa,Effendy,Pornchai Supnithi,Tsutomu Nagatsuma,Ken T. Murata +7 more
TL;DR: In this paper, the authors investigated the relationship between post-midnight F-region field aligned irregularities (FAIs) and F-layer altitude by analyzing data of a 30.8-MHz radar installed at Kototabang, Indonesia (0.2°S, 100.3°E; geomagnetic latitude 10.4°S).
Journal ArticleDOI
Relativistic electron flux forecast at geostationary orbit using Kalman filter based on multivariate autoregressive model
TL;DR: In this paper, a multivariate autoregressive model was used to forecast daily >2 MeV electron flux variations at geostationary orbit using a multiview model.
Journal ArticleDOI
Global MHD modeling of ionospheric convection and field‐aligned currents associated with IMF By triggered theta auroras
TL;DR: In this article, the authors investigate the evolution of ionospheric convection and field-aligned currents (FACs) when θ auroras are formed in response to interplanetary magnetic field (IMF) By transitions.
Journal Article
