Ionospheric Irregularities: Alaska Photometric Measurements

Abstract

Photometric measurements of auroral intensities and structure were made in Alaska during 1972 and 1973. Photometric data supporting the ICE CAP '73A operations are presented in terms of definition of the energy input to the ionosphere in the spatial vicinity of the rocket borne in situ experiments. Coordinated analysis of spatial and temporal variations of auroral emission intensities and electron densities are outlined using both photometric intensity data and incoherent scatter radar data. Analysis of time variations of 4278A, 5875A, and 4861A emission intensities observed in 1972 indicates strong substorm time correlation with the intensity peaks, but no indication of He emission in the 5875A spectral region was found. An analytical method for converting F region 6300A, OI emission intensity structure maps into radar effects structure information was demonstrated for a low latitude region pertinent to radar scintillation effects measurements at Kwajalein Missile Range.
