Three‐dimensional waveform modeling of ionospheric signature induced by the 2004 Sumatra tsunami
TLDR
In this article, the authors reproduce, with a 3D numerical modeling of the ocean-atmosphere-ionosphere coupling, the tsunami signature in the Total Electron Content (TEC) data measured by the Jason-1 and Topex/Poseidon satellite altimeters.Abstract:
[1] The Sumatra, December 26th, 2004, tsunami produced internal gravity waves in the neutral atmosphere and large disturbances in the overlying ionospheric plasma. To corroborate the tsunamigenic hypothesis of these perturbations, we reproduce, with a 3D numerical modeling of the ocean-atmosphere-ionosphere coupling, the tsunami signature in the Total Electron Content (TEC) data measured by the Jason-1 and Topex/Poseidon satellite altimeters. The agreement between the observed and synthetic TEC shows that ionospheric remote sensing can provide new tools for offshore tsunami detection and monitoring.read more

From Sumatra 2004 to Tohoku-Oki 2011: The systematic GPS detection of the ionospheric signature induced by tsunamigenic earthquakes
TL;DR: In this article, the authors highlight the early signature in the ionosphere produced by tsunamigenic earthquakes and observed by GPS, measuring the total electron content, close to the epicenter.

GNSS ionospheric seismology: Recent observation evidences and characteristics
TL;DR: In this paper, the authors used ground-based global navigation satellite system (GNSS) and space-borne GNSS Radio Occultation to investigate the seismo-ionospheric disturbances and may provide insights on the earthquake.

TL;DR: In this paper, the first observation of the airglow tsunami signature, resulting from the 11 March 2011 Tohoku earthquake off the eastern coast of Japan, was presented using a wide-angle camera system located at the top of the Haleakala Volcano on Maui, Hawaii They are correlated with GPS measurements of the total electron content from Hawaii GPS stations and the Jason-1 satellite.

Nrlmsise-00 Empirical Model of the Atmosphere: Statistical Comparisons and Scientific Issues
TL;DR: The new NRLMSISE-00 model and the associated NRLMSIS database now include the following data: (1) total mass density from satellite accelerometers and from orbit determination, including the Jacchia and Barlier data; (2) temperature from incoherent scatter radar, and; (3) molecular oxygen number density, [O2], from solar ultraviolet occultation aboard the Solar Maximum Mission (SMM).

International Reference Ionosphere 2000
TL;DR: The International Reference Ionosphere (IRI) is the international standard for the specification of ionospheric densities and temperatures as mentioned in this paper, which was developed and is being improved-updated by a joint working group of the International Union of Radio Science (URSI) and the Committee on Space Research (COSPAR).

TL;DR: Tsunami and geodetic observations indicate that additional slow slip occurred in the north over a time scale of 50 minutes or longer, and fault slip of up to 15 meters occurred near Banda Aceh, Sumatra, but to the north, along the Nicobar and Andaman Islands, rapid slip was much smaller.
