A new approach to the hourly mean computation problem when dealing with missing data
(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 ... -
Behaviour of the quiet day geomagnetic variation at Livingston Island and variability of the Sq focus position in the South American-Antarctic Peninsula region
(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 ... -

Multipoint observation of the response of the magnetosphere and ionosphere related to the sudden impulse event on 19 November 2007
(Journal of Space Weather Space Climate, 5, A13, 2015-05-18)The aim of this study is to provide a complete scope of a magnetic sudden impulse (SI) event along its way through interplanetary space and the magnetosphere until its arrival to the ground. In our case, ... -
SSC detection using wavelet analysis
(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 ...
