Abstract The Van Allen Probes Electric Fields and Waves (EFW) instrument provided
measurements of electric fields and spacecraft floating potentials over a wide dynamic range …

We present the first conjugate observations of subauroral ion drifts (SAID) in the
magnetosphere (∼ 9000 km altitude) and ionosphere and coincident measurements by four …

The assimilative mapping of ionospheric electrodynamics (AMIE) algorithm has been
applied to derive the realistic time‐dependent large‐scale global distributions of the …

Measurements of precipitating particles and the electric field on board EXOS D spacecraft
for the period January–June 1990 have been used for estimation of the diameter of the polar …

During the conjunctive SUNDIAL/ATLAS 1/GEM campaign period of March 28–29, 1992, a
set of comprehensive data has been collected both from space and from ground. The …

Electric and magnetic field variations inside the plasmasphere associated with SCs
identified on the ground are analyzed based on the Akebono satellite observations which …

Magnetic field, electric field, and electron density measurements from the Akebono satellite
are used to study the properties of two Pi2 pulsations that occurred in succession on …

During geomagnetically active times, the suprathermal mass spectrometer on the Akebono
satellite frequently observes upflowing molecular ions (NO+, N2+, O2+) in the 2‐3 Earth radii …

The distribution of the storm‐time electric field in the inner magnetosphere has been
investigated by using the Akebono/EFD data within a period from 1989 to 1995. During the …

Characteristics of field‐aligned currents (FACs) in the evening and morning regions during
the March 13–14, 1989, great magnetic storm have been determined using magnetic and …
