On the High-Energy Spectral Component and Fine Time Structure of Terrestrial Gamma Ray Flashes
M. Marisaldi, M. Galli, C. Labanti +13
Terrestrial gamma ray flashes (TGFs) are very short bursts of gamma radiation associated to thunderstorm activity and are the manifestation of the highest-energy natural particle a…
Gamma Ray Glow Observations at 20-km Altitude
N. Østgaard, H. J. Christian, J. E. Grove +12
In the spring of 2017 an ER-2 aircraft campaign was undertaken over continental United States to observe energetic radiation from thunderstorms and lightning. The payload consisted…
Time-scale dependence of solar wind-based regression models of ionospheric electrodynamics
K. M. Laundal, J. P. Reistad, S. M. Hatch +6
The solar wind influence on geospace can be described as the sum of a directly driven component, or dayside reconnection, and an unloading component, associated with the release of…
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…
Interplanetary Magnetic Field Component Influence on Horizontal and Field-Aligned Currents in the Ionosphere
K. M. Laundal, J. P. Reistad, C. C. Finlay +4
Statistical analyses have shown that the sunward component of the interplanetary magnetic field, (Geocentric Solar Magnetospheric), moderately but significantly af…
