Mean winds and tides have been measured with the new MF radar at London, Ontario. Using a 1-year continuous set of data, the mean winds are compared with a recent empirical model. The diurnal and semidiurnal tides are discussed, and these are compared with results from other similar midlatitude ground-based radars. There are interesting similarities and discrepancies, although we note that some of the initial comparisons use data from different years. The diurnal and semidiurnal tides are also compared with recent tidal models. Tidal characteristics are generally consistent with the models, but again some differences are also noted.
