AB: We present results from rocket borne in situ measurements of mesospheric turbulence obtained in the course of the international MIDAS/MacWave project. We apply a new data analysis technique based on wavelet analysis and identify turbulent layers with vertical extents from 100 m up to several kilometer. Our observations show that we observed the mesopause region in an extremely untypical dynamical state, in particular characterized by the fact that strong turbulence was observed below an altitude of 80 km. Evidence for this extraordinary behaviour is further identified in wind and temperature profiles obtained with meteorological rockets that accompanied the launches of the instrumented sounding rockets. Finally, we discuss our observations in the scope of current understanding of the role of breaking gravity waves for the dynamical and thermal structure of the mesopause region.
