HILION - A Model of the High-Latitude Ionospheric F2 Layer and Statistics of Regular Ionospheric Effects at Ft. Churchill, 1968,
Abstract
Part 1 of this report discusses HILION (HIgh Latitude IONosphere), an effort to model many features of the high-latitude ionospheric F2 layer with emphasis on the nighttime trough. The HILION modeling effort was undertaken in two main stages. The first stage was the modeling of many individual electron-density profiles using as input data values of electron density at various altitudes obtained by the Alouette I and II satellites. Programs were also developed to permit the similar modeling of Thomson Scatter data. The second stage was the ionospheric modeling proper, using the modeled profiles developed in the first stage as the input data. In the second study, F2 critical frequency data were assembled and statistically analyzed for the ionosphere above Ft. Churchill. The diurnal and seasonal variations of the peak critical frequency, foF2, have been depicted, and the possibility of determining foF2 at Ft. Churchill from either local or global parameters investigated.
