Abstract In the 95km height region of the atmosphere, ground-based techniques made an important contribution to the CIRA 72 [1] wind model. Recent wind measurements from a partial reflection experiment at 44S covering one and a half years are presented and compared with CIRA 72. The zonal wind component compares favourably, although the measured values are more easterly above 80km in autumn and winter; a feature of the autumn winds is a temporary easterly reversal above 90km. Winter mesospheric winds can be very disturbed. The summer mesosphere easterly maximum appears earlier in the season and at a higher altitude than the model. A much poorer comparison is shown between the measured meridional wind component and the 1969 model of Groves [2].
