Main Article Content
The detection of hydromagnetic waves on spacecraft and at the Earth's surface indicate disturbances of the geomagnetosphere. These disturbances are diagnostic of processes and boundaries occurring within the plasma of the Earth's space environment. In order to delineate the processes and boundaries a dense network of measuring points is desirable. Parameters that have proved useful are the frequency and the relative amplitudes and phases of the waves at different positions in space. This paper summarises some of the characteristics of hydromagnetic waves in the magnetosphere and the modification of the signal brought about by the boundary conditions imposed by the ionosphere-neutral atmosphere-Earth system.

This journal is one of a handful of scholarly journals that publish original scientific works under CC BY-NC-ND 4.0 - the only Creative Commons license affording the authors' intellectual property absolute worldwide protection.
Journal of Geophysics is published under the scholar-publishers model, meaning authors do not surrender their copyright to us. Instead, and unlike corporate publishers like Elsevier or Springer Nature that resell copyright to third-parties for up to $80,000 (per paper, per transaction!), the Journal of Geophysics authors share copyright equally with this journal.
Therefore, all the proceeds from reselling copyright to third parties get shared to equal parts (50% to the journal, 50% to the lead author). Under the Berne Convention, this protection is an inheritable right that lasts for as long as the rightsholder lives + 50 years.
By submitting to this journal, the lead author, on behalf of all co-authors, grants permission to this journal to represent all co-authors in negotiating copyright sales and collecting proceeds. The lead author should negotiate with his/her co-authors the modalities of distributing the lead author's portion of the proceeds. Usually, this is per pre-agreed percentage of each co-author's contribution to creating the copyrighted work. (more...)
