Abstract: This report presents results on wind and temperature profiles of the thermosphere determined by observing release of lithium, trimethyl-aluminium vapour and aluminised grenades from sounding rockets launched at Woomera. The drift and deformation of the trails are separated into large, medium and small scale motions. Their interpretation in terms of tides, gravity waves and turbulence is discussed. The high-altitude wind velocity limit revealed especially interesting results. Temperature profiles, determined by comparing observed vapour cloud spectra with synthetic spectra, are presented. They are in close agreement with standard atmosphere profiles for the corresponding exospheric temperatures.
