Ionospheric Signatures of Tohoku-Oki Tsunami of March 11, 2011: Model Comparisons Near the Epicenter
David A. Galvan,David A. Galvan,Attila Komjathy,Michael P. Hickey,Philip Stephens,Jonathan B. Snively,Y. Tony Song,Mark D. Butala,Anthony J. Mannucci +8 more
TL;DR: In this paper, the effect of the Tohoku earthquake and tsunami on the ionosphere near the epicenter was observed in measurements of ionospheric total electron content from 1198 GPS receivers in the Japanese GEONET network.
Journal ArticleDOI
Global plasmaspheric TEC and its relative contribution to GPS TEC
Endawoke Yizengaw,Mark B. Moldwin,David A. Galvan,B. A. Iijima,Attila Komjathy,Anthony J. Mannucci +5 more
TL;DR: In this article, the plasmaspheric electron content is directly estimated from the global positioning system (GPS) data onboard JASON-1 Satellite for the first time, and a global comparison between the two independent measurements was performed by dividing the data into three different regions; equatorial, mid-and high-latitude regions.
Journal ArticleDOI
Detecting ionospheric TEC perturbations caused by natural hazards using a global network of GPS receivers: The Tohoku case study
Attila Komjathy,David A. Galvan,Philip Stephens,Mark D. Butala,Vardan Akopian,Brian Wilson,Olga P. Verkhoglyadova,Anthony J. Mannucci,Michael P. Hickey +8 more
TL;DR: In this article, a real-time Global Assimilative Ionospheric Model (GAIM) system was proposed to monitor TEC fluctuations using JPL's real-term Global Assimilation Model (GOMA) system.
Journal ArticleDOI
The 2009 Samoa and 2010 Chile tsunamis as observed in the ionosphere using GPS total electron content
TL;DR: In this article, ground-based Global Positioning System (GPS) measurements of ionospheric total electron content (TEC) show variations consistent with atmospheric internal gravity waves caused by ocean tsunamis following two recent seismic events: the Samoa earthquake of 29 September 2009 and the Chile earthquake of 27 February 2010.
Journal ArticleDOI
The correlation between mid-latitude trough and the plasmapause
E. Yizengaw,Hanying Wei,Mark B. Moldwin,David A. Galvan,Lukas Mandrake,Anthony J. Mannucci,Xiaoqing Pi +6 more
TL;DR: In this article, simultaneous global observations of the mid-latitude trough and the plasmapause were used to experimentally prove a long-standing conjecture of magnetosphere-ionosphere coupling.
