Machine Learning Solar Wind Driving Magnetospheric Convection in Tail Lobes
Xin Cao, Jasper S. Halekas, Stein Haaland +2
To quantitatively study the driving mechanisms of magnetospheric convection in the magnetotail lobes on a global scale, we utilize data from the ARTEMIS spacecraft in the deep tail…
Prediction of soft proton intensities in the near-Earth space using machine learning
Elena A. Kronberg, Tanveer Hannan, Jens Huthmacher +14
The spatial distribution of energetic protons contributes towards the understanding of magnetospheric dynamics. Based upon 17 years of the Cluster/RAPID observations, we have deriv…
Prediction and understanding of soft proton contamination in XMM-Newton: a machine learning approach
E. A. Kronberg, F. Gastaldello, S. Haaland +10
One of the major and unfortunately unforeseen sources of background for the current generation of X-ray telescopes are few tens to hundreds of keV (soft) protons concentrated by th…
Separation and Quantification of Ionospheric Convection Sources: 1. A New Technique
J. P. Reistad, K. M. Laundal, N. Østgaard +4
This paper describes a novel technique that allows separation and quantification of different sources of convection in the high-latitude ionosphere. To represent the ionospheric co…
Separation and Quantification of Ionospheric Convection Sources: 2. The Dipole Tilt Angle Influence on Reverse Convection Cells During Northward IMF
J. P. Reistad, K. M. Laundal, N. Østeward +5
This paper investigates the influence of Earth's dipole tilt angle on the reverse convection cells (sometimes referred to as lobe cells) in the Northern Hemisphere ionosphere durin…
Dayside and nightside magnetic field responses at 780 km altitude to dayside reconnection
K. Snekvik, N. Østgaard, P. Tenfjord +4
During southward interplanetary magnetic field, dayside reconnection will drive the Dungey cycle in the magnetosphere, which is manifested as a two-cell convection pattern in the i…
Birkeland current effects on high-latitude groundmagnetic field perturbations
K. M. Laundal, S. E. Haaland, N. Lehtinen +8
Magnetic perturbations on ground at high latitudes are directly associated only with the divergence-free component of the height-integrated horizontal ionospheric current, $\textbf…
Characteristics of the flankmagnetopause: Cluster observations
S. Haaland, J. Reistad, P. Tenfjord +6
The magnetopause is a current sheet forming the boundary between the geomagnetic field on one side and the shocked solar wind on the other side. This paper discusses properties of…
Solar illumination control of ionospheric outflow above polar cap arcs
L. Maes, R. Maggiolo, J. De Keyser +4
We measure the flux density, composition, and energy of outflowing ions above the polar cap, accelerated by quasi-static electric fields parallel to the magnetic field and associat…
Oxygen and hydrogen ion abundance in the near-Earth magnetosphere: Statistical results on the response to the geomagnetic and solar wind activity conditions
Elena A. Kronberg, Stein E. Haaland, Patrick W. Daly +4
The composition of ions plays a crucial role for the fundamental plasma properties in the terrestrial magnetosphere. We investigate the oxygen-to-hydrogen ratio in the near-Earth m…
