We review evidence gathered from theoretical considerations and from measurements on the ground and in space for a 90° rotation of the major axis of the polarization ellipse of geomagnetic pulsation signals between the geomagnetic equator and the ground. The evidence at present supports the existence of the rotation phenomenon, although more observational work is needed. The rotation arises from the nonconducting air on the ground surface and the highly conducting plasma in space.
