Abstract The Super Dual Auroral Radar Network (SuperDARN) is a network of high-
frequency (HF) radars located in the high-and mid-latitude regions of both hemispheres that …

Meso-scale auroral forms, such as poleward boundary intensifications, streamers, omega
bands, beads and giant undulations, are manifestations of dynamic processes in the …

Auroral substorms are often associated with optical ray or bead structures during initial
brightening (substorm auroral onset waves). Occurrence probabilities and properties of …

This chapter reviews recent findings of multi‐scale structures and dynamics in the high‐
latitude ionosphere, particularly on meso‐scale (10s‐100s km) processes, as well as their …

In the auroral E‐region strong electric fields can create an environment characterized by fast
plasma drifts. These fields lead to strong Hall currents which trigger small‐scale plasma …

In data mining, density-based clustering, which entails classifying datapoints according to
their distributions in some space, is an essential method to extract information from large …

Auroral observations were first to identify the substorm, and later used to propose that
substorm onset is triggered in the inner plasma sheet (equatorward portion of the auroral …

We present observations during two substorms using simultaneous Time History of Events
and Macroscale Interactions During Substorms satellites and all‐sky imagers to determine …

About 40 years after the discovery of the substorm, auroral observations were used to
propose that substorm onset was triggered in the inner plasmas sheet (equatorward portion …

A fortuitous configuration of five Time History of Events and Macroscale Interactions during
Substorms probes indicated that on 15 February 2008 between 04: 00 and 11: 00 UT a BZ …
