Description:
During the International Polar Year (IPY), one area of great interest is co-coordinated, multi-instrument probing of the ionosphere at high latitudes. This region is important
not only for the applications that rely upon our understanding of it, but also because it
contains the footprints of processes that have their origin in the interplanetary space. Many different techniques are now available for probing the ionosphere, from radar measurements to the analysis of very low frequency (VLF) wavepaths. Combining
these methods provides the ability to study the ionosphere from high in the F-region to
the bottom of the D-layer. Thus, coupling processes from the magnetosphere and to the
neutral atmosphere can be considered. An additional dimension is through comparisons
of the response of the two polar ionospheres to similar (or the same) geomagnetic
activity. With more instruments available at the South Pole inter-hemispheric, studies
have become easier to accomplish such that a fuller picture of the global response to
Sun–Earth coupling can be painted.
This paper presents a review of the current state of knowledge in ionospheric
probing. It cannot provide a comprehensive guide of the work to date due to the scale of
the topic.Rather it is intended to give an overview of the techniques and recent results
from some of the instruments and facilities that are a part of the IPY cluster
63—Heliosphere Impact on Geospace. In this way it is hoped that the reader will gain a
flavor of the recent research performed in this area and the potential for continuing
collaboration and capabilities during the IPY (2007–2009).
