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…

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…
