A Merged Search‐Coil and Fluxgate Magnetometer Data Product for Parker Solar Probe FIELDS [PDF]

open access: yesJournal of Geophysical Research: Space Physics, 2020
AbstractNASA's Parker Solar Probe (PSP) mission is currently investigating the local plasma environment of the inner heliosphere (<0.25 R⊙) using both in situ and remote sensing instrumentation. Connecting signatures of microphysical particle heating and acceleration processes to macroscale heliospheric structure requires sensitive measurements of ...

Chorus source region localization in the Earth's outer magnetosphere using THEMIS measurements [PDF]

open access: yesAnnales Geophysicae, 2010
Discrete ELF/VLF chorus emissions, the most intense electromagnetic plasma waves observed in the Earth's radiation belts and outer magnetosphere, are thought to propagate roughly along magnetic field lines from a localized source region near the ...

Tectonomagnetic and VLF electromagnetic signals in Central Italy

open access: yesAnnals 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.

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

open access: yesAnnales 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]

open access: yesJournal 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 ...

Experimental study of 199Hg spin anti-relaxation coatings

open access: yes, 2013
We report on a comparison of spin relaxation rates in a $^{199}$Hg magnetometer using different wall coatings. A compact mercury magnetometer was built for this purpose.
