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…
On the timing between terrestrial gamma ray flashes, radio atmospherics, and optical lightning emission
Thomas Gjesteland, Nikolai Østgaard, Phillip Bitzer +1
On 25 October 2012 the Reuven Ramaty High Energy Solar Spectroscope Imager (RHESSI) and the Tropical Rainfall Measuring Mission (TRMM) satellites passed over a thunderstorm on the…
Constraints to do realistic modeling of the electric field ahead of the tip of a lightning leader
Alexander Broberg Skeltved, Nikolai Østgaard, Andrew Mezentsev +2
Several computer models exist to explain the observation of terrestrial gamma-ray flashes (TGFs). Some of these models estimate the electric field ahead of lightning leaders and it…
North-south asymmetries in cold plasma density in the magnetotail lobes: Cluster observations
S. Haaland, B. Lybekk, L. Maes +7
In this paper, we present observations of cold (0-70 eV) plasma density in the magnetotail lobes. The observations and results are based on 16 years of Cluster observation of space…
Defining and resolving current systems in geospace
N. Y. Ganushkina, M. W. Liemohn, S. Dubyagin +15
Electric currents flowing through near-Earth space ( 12 ) can support a highly distorted magnetic field topology, changing particle drift paths an…
