In this paper we use a fully coupled ULF wave model to determine the ratio eveq/bvg for a 5 mHz FLR formed at high latitudes. We find that Ozeke et al. (2009) underestimated the ULF wave magnetic field on the ground which varies with ionosphere Hall conductance. This difference is found to be caused by assuming a decoupled wave mode model for the ionosphere fields. Any relationship that involves ULF wavefields in the ionosphere must include the effects of ULF wave mode mixing.]]> Wed 11 Apr 2018 12:31:29 AEST ]]> Field line resonant frequencies and ionospheric conductance: results from a 2-D MHD model https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:4837 Wed 11 Apr 2018 12:12:48 AEST ]]> Quarter-wave modes of standing Alfvén waves detected by cross-phase analysis https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:4836 Wed 11 Apr 2018 11:44:59 AEST ]]> Energization of outer radiation belt electrons during storm recovery phase https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:27694 10 keV electrons during the early recovery phase of a moderate geomagnetic storm. We find that internal energization of equatorially mirroring electrons via nonresonant ULF wave-particle interactions can explain these observations. The wave poloidal components cause radial drift of electrons, increasing (decreasing) their kinetic energy as they move inward (outward). Electrons with initial kinetic energies of a few keV can be energized to double these values within an hour by interaction with the 3 mHz waves. The energization rate is somewhat less for the 4-5 mHz waves. An increase in the ionospheric conductance decreases the power of the fast mode wave, reducing radial drift velocities and hence decreasing the rate of energization. The fast mode poloidal field varies with radial distance and longitude, and this also affects energization. Electrons which drift outward encounter a region where the toroidal field due to the field line resonance becomes dominant and produces strong azimuthal drift. These electrons become trapped in an L-shell range just outward of the resonance region and are not energized.]]> Wed 11 Apr 2018 11:43:08 AEST ]]> Effects of the magnetic field model and wave polarisation on the estimation of proton number densities in the magnetosphere using field line resonances https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:3305 Wed 11 Apr 2018 11:08:02 AEST ]]> Revised time-of-flight calculations for high-latitude geomagnetic pulsations using a realistic magnetospheric magnetic field model https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:3311 Wed 11 Apr 2018 09:40:09 AEST ]]> Doppler clutter in HF radar systems produced by ULF waves https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:14033 Wed 11 Apr 2018 09:25:20 AEST ]]> ULF modulation of EMIC in the inner magnetosphere https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:47981 Wed 06 Mar 2024 15:18:25 AEDT ]]> Numerical investigations of interhemispheric asymmetry due to ionospheric conductance https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:37696 Tue 16 Mar 2021 17:37:59 AEDT ]]> Transverse-scale size of Pc3 ULF waves near the exterior cusp https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:7818 Sat 24 Mar 2018 08:37:35 AEDT ]]> Electromagnetic ion cyclotron waves in the magnetosphere https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:2240 Sat 24 Mar 2018 08:29:03 AEDT ]]> Magnetoseismology: ground-based remote sensing of Earth's magnetosphere https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:15487 Sat 24 Mar 2018 08:21:27 AEDT ]]> A study of polar cap Pc1-2: source locations and wave propagation https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:12033 Sat 24 Mar 2018 08:08:34 AEDT ]]> Magnetospheric ULF waves: a review https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:17429 Sat 24 Mar 2018 08:01:40 AEDT ]]> Results from a MHD model of ultra low frequency waves in the magnetosphere with realistic ionospheric conductances https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:5940 Sat 24 Mar 2018 07:48:25 AEDT ]]> The outer radiation belt injection, transport, acceleration and loss satellite (ORBITALS): A Canadian small satellite mission for ILWS https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:3478 Sat 24 Mar 2018 07:20:27 AEDT ]]> Modeling the Effects of Drift Shell Splitting in Two Case Studies of Simultaneous Observations of Substorm-Driven Pi1B and IPDP-Type EMIC Waves https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:53274 Mon 20 Nov 2023 12:55:57 AEDT ]]>
