    • Behaviour of the quiet day geomagnetic variation at Livingston Island and variability of the Sq focus position in the South American-Antarctic Peninsula region 

      Torta, J.M.; Marsal Vinadé, Santiago; Curto, J.J.; Gaya-Piqué, L.R (2009-08-24)
      The characteristics of the regular daily variation at the relatively new geomagnetic observatory of Livingston Island have been studied. They include the seasonal and solar cycle variabilities. Studies ...

(International Workshop “Challenges for Geomagnetism, Aeronomy and Seismology in the XXI Century". Roquetes (Baix Ebre), 29 Septiembre-1 Octubre 2004], 2004-10-01)
      Activities of research and services are performed at the magnetic section of Ebro Observatory. Most of the scientific projects are related to Solar_terrestrial Physics. Latest projects focused on Antarctic ...

    • Midlatitude F region peak height changes in response to interplanetary magnetic field conditions and modeling results 

      Blanch Llosa, Estefania; Altadill, David (Blanch, E., and D. Altadill (2012), Midlatitude F region peak height changes in response to interplanetary magnetic field conditions and modeling results, J. Geophys. Res., 117, A12311, doi:10.1029/2012JA018009., 2012-12-13)
      The response of the electron density peak height of the F2 region, hmF2, to geomagnetic storms has been investigated and a characteristic behavior of the peak height disturbance in relation to local-time, ...

    • SSC detection using wavelet analysis 

      Curto, J.J.; Blanch Llosa, Estefania (International Workshop “Challenges for Geomagnetism, Aeronomy and Seismology in the XXI Century". Roquetes (Baix Ebre), 29 Septiembre-1 Octubre 2004, 2004-10-01)
      For Sudden Storm Commencements, several methods aiming automatic detection of the events have been proposed. Most of them are based in the analysis of digital geomagnetic field data using some morphological ...
