A comparison of EISCAT and HF Doppler observations of a ULF wave
journal contribution
posted on 2015-03-18, 11:20 authored by D. M. Wright, Tim K. Yeoman, J. A. DaviesSince the middle of 1995, an HF Doppler
sounder has been running almost continuously in
northern Norway, with the receiver at Ramfjordmoen
and the transmitter at Seljelvnes. Concurrent operation
of the EISCAT UHF radar in common programme
(CP-1) mode has made it possible to study the ionospheric
signature of a magnetospheric ULF wave. These
are the first results of such wave signatures observed
simultaneously in both instruments. It has been demonstrated
that the observed Doppler signature was
mainly due to the vertical bulk motion of the ionosphere
caused by the electric field perturbation of the ULF
wave and the first direct observational confirmation of a
numerical simulation has been achieved. The wave,
which was Alfvénic nature, was detected by the
instruments 8° equatorward of the broad resonance
region. The implications for the deduced wave modes in
the ionosphere and the mechanism producing the HF
Doppler variations are discussed.
