Abstract The ionospheric convection electric field is often assumed to be a potential field. This assumption is not always valid, especially when the ionosphere changes on short time scales T≲5 min. We present a technique for estimating the inducti

Auroral oval identification based on Swarm magnetometer data

Autor: Margot Decotte, Spencer Hatch, Karl Laundal, Jone Reistad

Following the work done with the DMSP spectrometer data to derive the auroral occurrence probability in all covered MLat-MLT sectors above 50 degrees MLat (Decotte et al. 2023), here we use the Swarm magnetometer data to extract the probability to de

The relationship between dayside and nightside Dynamics under northward interplanetary magnetic field substorms

Autor: Reham Elhawary, Karl Laundal, Jone Reistad, Anders Ohma, Spencer Hatch, Sara Gasparini

Substorms that occur under northward interplanetary magnetic field (IMF) conditions can elucidate the relationship between the dayside and nightside dynamics of the ionosphere. We investigate the relationship between the dayside and the nightside dyn
