Abstract

Results of partial reflection wind measurements in the lower inosphere at Juliusruh (54.6 N, 13.4 E) are described. Height-time cross sections of the prevailing wind and the semidiurnal tide in the height region between 73 and 90 km determined during winter and spring in 1989 and 1990 are discussed. Comparisons of the results with corresponding wind values observed by ionospheric drift measurements in the LF-range at Collm (about 370 km apart) show a good agreement in the 30 minutes mean values as well as in the prevailing wind and semidiurnal tide and allow the estimation of wind profiles from 75 km to about 110 km. Further, comparisons with wind results from meteorological rockets launched at Zingst (about 40 km apart) up to a height of about 70 km indicate the possibility of obtaining combined wind profiles over the height range from 25 to 90 km.
