      A vertical incidence sounder (VIS) was installed at the Spanish Antarctic Base (62.7°S, 299.6°E) during the Antarctic summer survey 2004–2005. In addition, an oblique sounding (OS) system for HF ...

    • A new approach to the hourly mean computation problem when dealing with missing data 

      Marsal Vinadé, Santiago; Curto, J. J. (Earth Planet Sp (2009) 61: 945, 2009-10-19)
      Geomagnetic observatory records are unavoidably affected by primary data interruptions which, in turn, may have possible effects on the accuracy of the definitive data derived from them. One of the ...

    • 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, ...
