A review of the impact of the cold-ion and cold-electron populations in the Earth's
magnetosphere is presented. The cold populations are defined by total energy less than …

This paper reviews key properties and major unsolved problems about Strong Thermal
Emission Velocity Enhancement (STEVE) and the picket fence. We first introduce the basic …

We present the first observations of ionospheric phenomena using the newly deployed
Transition Region Explorer (TREx) Spectrograph. On the night of 10 April 2018, STEVE …

We report on a novel scenario of subauroral arcs within strong subauroral ion drifts (SAID)‐
STEVE and Picket Fence. Their explanation requires a local source of low‐energy, ε< 18.75 …

During the 17 March 2015 geomagnetic storm, citizen scientist observations from Dunedin
(45.95° S, 170.32° E), New Zealand, revealed a bright wide red arc known as stable auroral …

We present a unified approach to subauroral arcs within intense subauroral ion drifts (SAID),
which explains the observed transition of a precursor Stable Auroral Red (SAR) arc into …

We found the inner electromagnetic structure of subauroral ion drifts (SAID) in the SAID‐
STEVE events documented by the Swarm spacecraft and numerically simulated the …

Optical structures located equatorward of the main auroral oval often exhibit different
morphologies and dynamics than structures at higher latitudes. In some cases, questions …

An assessment of the status quo of fast subauroral flows—subauroral ion drifts (SAID) and
subauroral polarization streams (SAPS), is presented. For a few decades, their development …

Land surface processes are strongly associated with heat waves (HWs). However, how the
uncertainties in land surface processes owing to inaccurate physical parameters influence …
