Event Title

A Comparison of Height-Integrated Ionospheric Currents and Magnetic Perturbation in the Auroral Zone

Location

Yosemite National Park

Description

Data taken by the Incoherent Scatter Radar facility at Chatanika, Alaska (L=5.6,A=65°) have been used to study E-region height-integrated conductivities and currents. It is found that the radar measurements agree well with the magnetic H-component measured by the nearby magnetometer at college. Fairly large discrepancies occur between the radar data and the D component measured at college, indicating that field aligned currents are present. It is also found that the neutral wind is important, particularly during daytime, in driving a portion of the ionospheric currents.
