On the response of fading times of upper homosphere radar echoes to solar and geomagnetic disturbances

Abstract
Four years of auroral latitude radar echo signal fading time data from the Tromsø MF radar compared with geomagnetic and solar indices yield strong evidence to suggest, although not prove, that upper mesospheric turbulence may be enhanced during periods of geomagnetic activity. We present a critique of hypotheses to explain such effects.
