This made possible to test the ionospheric Alfven resonator (JAR) model over a large altitude range. The three lowest JAR eigenfrequencies, where the most of the Pc1 pulsation signal bands occur, were selected for the spatial analysis of the standing wave electromagnetic fields, applying the full-wave numerical simulation method. The altitude spread of amplitude maxima and nodes together with polarization characteristics of oscillation maxima in the horizontal plane are presented The comparison of the standing wave oscillations on the altitude profile with the signal amplitude observed on the ground is also presented.
