The Influence of Geomagnetic Activity on the Day-to-Day Variability of the Ionospheric F-Region.
Abstract
This report describes a summary of preliminary findings concerning the search for a geomagnetic activity control of ionospheric variability. The results are encouraging in that the division of a month's worth of F-region data into a geomagnetically ordered hierarchy may lead to a satisfactory forecasting scheme for day-to-day variability. The five geomagnetically quiet days of the month (QQ-days) were seen to behave in a consistent way for seasons and stations where the disturbed days had a well-defined pattern. The geomagnetic storm associated disturbed days within a month are themselves best handled by superimposed epoch derived average storm patterns for each day of a storm period. Thus, if storm days and QQ days are removed from a monthly distribution, the remaining 15-20 days may either fall within acceptable variability limits or lend themselves to 'QQ-like' 'DD-like' classifications.
