Analysis of the Geomagnetic Induction Tensor
T'ne geomagnetic induction tensor is a means of summarizing the response of the earth at a given observing site to a geomagnetic variation source field. In this paper the characteristics of the tensor elements are examined, both generally and for the special cases of one-dimensional and two-dimensional geologic structure. The first-order model is taken of uniform source fields originating exter...
متن کاملSolar eclipse effect on geomagnetic induction parameters
The 11 August 1999 total solar eclipse had been studied using a large array of stations in Central Europe (Bencze et al., 2005). According to the result of this study, the amplitudes of the field line resonance (FLR)-type pulsations decreased in and around the dark spot by about a factor of 2, and this decrease moved with the velocity of the dark spot in the same direction. This decrease was in...
متن کاملThe role of 3-D geomagnetic induction in the determination of the ionospheric currents from the ground geomagnetic data
The geomagnetic field variations measured at the surface of the Earth are composed of both internal and external parts. The external field arises from the sources in the magnetosphere and ionosphere, whereas the internal field is generated by the currents induced within the Earth. The internal part may in some situations comprise a notable part of the measured total field and thus a blind usage...
متن کاملGeomagnetic induction and conductive structures in north - west India
Magnetic disturbance events and quiet daily variation as recorded by the 1979 magnetometer array study in north-west India are analysed for evidence of electrical conductivity structures in the region. Contour maps of Fourier transform parameters are presented, and the disturbance event data are also reduced to sets of real and quadrature Parkinson arrows over a range of periods. A variety of c...
متن کاملOn the interpretation of the distinctive pattern of geomagnetic induction observed in northwest India
Chamalaun, F.H., Prasad, S.N., Lilley, F.E.M., Srivastava, B.J., Singh, B.P. and Arora, B.R., 1987. On the interpretation of the distinctive pattern of geomagnetic induction observed in northwest India. Tectonophysics, 140: 247-255. The geomagnetic variation data from the 1979 Indian array experiment have been reanalyzed and reexamined using the hypothetical event analysis technique. The contou...
