Earth–ionosphere couplings, magnetic storms, seismic precursors and TLEs: Results and prospects of the [SQUID]2 system in the low-noise underground laboratory of Rustrel-Pays dʼApt
[Couplages Terre–ionosphère, orages magnétiques, précurseurs sismiques et sylphes : résultats et prospects du système [SQUID]2 au laboratoire souterrain de Rustrel-Pays dʼApt]
Comptes Rendus. Physique, Volume 12 (2011) no. 2, pp. 192-202.

Grâce à sa sensibilité et son environnement très bas bruit, les couplages Terre–ionosphère sont observables par le magnétomètre [SQUID]2 (Superconducting QUantum Interference Device with Shielding QUalified for Ionosphere Detection). Notamment :

  • – un mode de résonance de la mésopause excitable par les ondes P ou par champ électrique comme dans lʼheure précédant le séisme de Sichuan en mai 2008 ;
  • – les modes S et T de respiration du globe pendant des périodes de calme magnétique et sismique ;
  • – lʼintégrale mondiale du signal des orages magnétiques y compris les contributions polaires ;
  • – des signaux associés aux sylphes.
Ceci permet dʼenvisager un réseau mondial de quelques stations de même type.

High sensitivity combined with an ultra-low-noise environment [SQUID]2 magnetometer (Superconducting QUantum Interference Device with Shielding QUalified for Ionosphere Detection) allows the observation of Earth–ionosphere couplings. Namely:

  • – identification of a mesopause resonance mode excitable by P waves or by electric field as during the hour before the Sichuan earthquake (May 2008);
  • – S and T breathing modes of the Earth during quiet magnetic and seismic periods;
  • – worldwide signal integral of magnetic storms including polar contributions;
  • – signals in time correlation with sprites (Transient Luminous Events).
These results point to a worldwide network of at least a few stations of a similar type.
