Correlation of Auroral Substorm Particle Spectra with Associated Atmospheric Effects.
Abstract
Results are presented from a study of the correlation of auroral zone rocket-measured particle spectra with the associated atmospheric effects. Particle results from three substorms at Ft. Churchill, Canada in 1970-72 are presented, and the 1970 event is analyzed in detail. Emphasis is placed on 3914 A optical emission and 30 MHz RF absorption. Particle spectra in the 1-15 keV region are used to calculate the resulting total 3914 A emission, and this is correlated with results from ground-based photometers. A general method of calculating the altitude profile of energy deposition due to energetic electrons is given, including both collisional and bremsstrahlung effects. The method is used in development of expressions for high frequency riometer absorption. It is then applied to the rocket measured energetic (greater than 15 keV) electron spectra, and results are compared with those from the ground-based polar riometer.
