Appendix N2 - The behavior of the ionospheric F-region during geomagnetic storms is addressed by examining many years of total electro content (TEC) data obtained from a semi-global network of TEC observing sites. An analysis procedure is described which leads to the derivation of average disturbance patterns which capture the "characteristic features" see during individual storms. These average storm patterns give percetage deviations from monthly median behavior on a local time basis over a 4-day storm period ER -
