Option prices can be used to construct implied (risk-neutral) distributions, but it remains to
be proven whether these are useful either in relation to forecasting subsequent market …

The large‐scale field‐aligned currents (FAC) as reported earlier from the Triad magnetometer
data received at College, Alaska (lijima and Potemra, 1976a, b), are also observed in the …

Low‐ and high‐altitude spacecraft carrying scientific magnetometers have probed the
magnetic fields of the terrestrial magnetosphere. These measurements reveal that field‐aligned …

Relationships between convective electric fields, Birkeland currents, and ionospheric conductivity
at high latitudes are investigated by using simultaneous measurements of electric and …

Vector magnetic field observations made with the three‐axes magnetometer on the Triad
satellite have been used to study the orientation of magnetic disturbances in the dayside polar …

The high spatial-temporal resolution of instrumentation on the polar-orbiting S3-2 satellite has
allowed a wide variety of measurements of the electrodynamic characteristics of both large…

During his polar expeditions of 1902–1903, Kristian Birkeland determined that large-scale
ionospheric currents were associated with the aurora. Birkeland suggested that these currents …

Small‐scale transverse magnetic field disturbances are often observed with the magnetometer
experiment on board the Triad satellite at latitudes poleward of the large‐scale field‐…

Nearly simultaneous observations from the Triad and Hawkeye spacecraft at low altitudes
over the south polar cap show that in and near the polar cusp there exist several relationships …

Simultaneous observations of field‐aligned currents (FAC) and auroral kilometric radiation (AKR)
are compared from the polar‐orbiting satellites Triad and Hawkeye. The Triad …
