Structure of the poleward wall of the trough and the inclination of the geomagnetic field above the EISCAT radar
International audience A special high-resolution routine of the EISCAT radar has been used to investigate the structure and development of the poleward wall of a deep trough in electron density. The feature was tracked by the radar during a 7-hour period under very quiet geomagnetic conditions. The...
