For each case, we consider the model’s input data, the output parameters, products or services, its operational status, and whether it is supported by validation results, in order to build a solid basis for future developments. This work is the output of the Sub Group 1.3 ‘‘Improvement of operational models’’ of the European Cooperation in Science and Technology (COST) Action ES0803 ‘‘Developing Space Weather Products and services in Europe’’ and therefore this review focuses on the progress achieved by European research teams involved in the action.429 422 - PublicationOpen AccessA case study of global ULF pulsations using data from space-borne and ground-based magnetometers and a SuperDARN radar(2011)
; ; ; ; ; ; ; ; ;On 21—22 January 2005 global ULF pulsations in the Pc5 range were observed in the Earth’s magnetosphere. The event took place during a compact high velocity stream of the solar wind, which produced a moderate magnetospheric storm and was characterised by mainly positive values of the interplanetary magnetic field Bz component and by dense plasma. To study the wave field structure of the ULF oscillations during this event we used magnetometer data from the GOES-10 and GOES-12 geostationary satellites, line of sight velocity data from the Kodiak SuperDARN radar, and magnetic measurements from INTERMAGNET observatories. In order to analyse the wave structure along a magnetic field line, GOES measurements were compared with those of ground stations closest to the GOES magnetic foot prints, while the Kodiak measurements were compared with magnetic field data from two INTERMAGNET stations, College and Shumagin, which were located within the Kodiak field of view or very close to it. The study shows a good correspondence and even coherence for some frequency components between pulsations observed near the top of a field line and at its foot and, to a lesser extent, between Kodiak line of sight velocities and conjugated magnetic measurements.57 16 - PublicationOpen AccessOn the excitation of magnetic signals by Love waves(2004)
; ; ; ;Guglielmi, A. V.; Schmidt United Institute of Physics of the Earth, Russian Academy of Sciences, Moscow, Russia ;Potapov, A. S.; Institute of Solar-Terrestrial Physics, Siberian Branch of the Russian Academy of Sciences, Irkutsk, Russia ;Tsegmed, B.; Astronomy and Geophysics Research Center, Mongolian Academy of Sciences, Ulaanbaatar, Mongolia; ; The polarization method for recognition of seismomagnetic waves against a noise background is presented. The method is applied to detection of magnetic oscillations accompanying the propagation of surface Love wave after a strong earthquake. A specific property of the Love waves is that theoretically the Tolman-Stewart effect is alone responsible for the magnetic field that penetrates into the Earth's surface. Data from the Mondy Magnetic Observatory and the Talaya Seismic Station suggest that the arrival time, duration, period,and polarization of magnetic signals conform with the idea of generation of alternating electric currents due to fluid vibrations in pores and fractures of rocks under the action of the inertial force associated with the Love wave propagation.133 206
