Abstract:

Spectrophotometric measurements of the auroral emission intensities in several wavelength regions were made at Chatanika Alaska during observing periods in 1978 through 1980. Specific experiments reported herein include measurements of the temporal and spatial power spectral densities and associated statistical quantities for auroral emission irregularities which occurred during the development, intensification, and decay of a poleward expansion characterization of the precipitating electron flux, total energy deposit and mean energy parameter, and the response of the ionosphere during an intense pulsating aurora, and observation of the precipitating electron flux characteristics and the ionospheric response over a period of decaying precipitation intensity located at the poleward edge of the aurora oval. Both of the latter measurements were conducted as coordinated experiments with the Chatanika incoherent scatter radar.
