Tectonomagnetic and VLF electromagnetic signals in Central Italy

Annals of Geophysics, 2004
Tectonomagnetic field observations from absolute magnetic field level measurements were undertaken in Central Italy in an area extending between latitude 41°N and 43°N and between longitude 13°E and 15°E.

First results of low frequency electromagnetic wave detector of TC-2/Double Star program [PDF]

Annales Geophysicae, 2005
LFEW is a low frequency electromagnetic wave detector mounted on TC-2, which can measure the magnetic fluctuation of low frequency electromagnetic waves. The frequency range is 8 Hz to 10 kHz.

Determination of wave vectors using the phase differencing method [PDF]

Annales Geophysicae, 2013
Due to the collisionless nature of space plasmas, plasma waves play an important role in the redistribution of energy between the various particle populations in many regions of geospace. In order to fully comprehend such mechanisms it is necessary to

Searching for ULF signatures of the cusp: Observations from search coil magnetometers and auroral imagers in Svalbard [PDF]

Journal of Geophysical Research: Space Physics, 2009
Spacecraft traveling through the cusp at a variety of altitudes have consistently found the cusp to be filled with intense, often irregular power in the upper ULF frequency range. Some ground‐based studies have observed narrowband waves in this same frequency range in the vicinity of the cusp foot point, but it has not been possible with magnetometers ...

Evolution of magnetotelluric, total magnetic field, and VLF field parameters in Central Italy: relations to local seismic activity

Annals of Geophysics, 2001
Magnetotelluric data were collected at Collemeluccio (41.72°N, 14.37°E) in Central Italy from summer 1991 to spring 1998. Analyzed by means of tensor decomposition on the geoelectric potential and robust estimation on the geomagnetic field, this set of ...

Use of the International Reference Ionosphere 2012 model to calculate emission frequency scale of the ionospheric Alfvén resonator

Journal of Space Weather and Space Climate, 2015
We apply the IRI-2012 version of the International Reference Ionosphere model to calculate the difference between frequencies of adjacent harmonics (frequency scale) of the ionospheric Alfvén resonator (IAR) emission.

Spaced‐based search coil magnetometers

Journal of Geophysical Research: Space Physics, 2016
AbstractSearch coil magnetometers are one of the primary tools used to study the magnetic component of low‐frequency electromagnetic waves in space. Their relatively small size, mass, and power consumption, coupled with a good frequency range and sensitivity, make them ideal for spaceflight applications.
