Solar Cycle Variations Observed in the High-Latitude Ionosphere
Abstract
We have prepared an 11 year record of the high-latitude ionospheric environment using the AMIE data assimilation technique driven primarily by ground magnetometers. Using this data set we examine the difference in the response of the high-latitude ionosphere to similar input events as identified by IMF Bz, By, V, and density profiles. We look at the effect of the phase of the solar cycle, season, and other long time scale variations. We present the results as identified modes of the ionosphere and discuss the evolution from one to another over the scale of a solar cycle.
