The Construction of Storm-Time Corrections for Ionospheric F-Region Parameters and Their Application to Trans-Ionospheric Group-Path Delay.
Abstract
A two-part investigation of magnetic storm effect upon the mid-latitude ionosphere has been carried out using as its data the AFCRL Atlas of storm effects in the F-region parameters total electron content (TEC), peak density (N sub max) and equivalent slab thickness (tau). Part I deals with the problem of applying average storm patterns (in percent) as predictions for storm-time corrections to existing TEC, N sub max, and tau models used in various propagation systems. Part II describes an analysis performed to determine the extent of trans-ionospheric group delay enhancements at 1600 MHz associated with the so-called 'Positive ionospheric disturbances' in TEC induced by geomagnetic storms. Statistical summaries are presented which describe the magnitude, duration and local time dependence of the enhancements in group delay (delta tau), measured with respect to predicted values which do not take magnetic activity into account.
