For the solar minimum years 1985-1987, values of meridional wind at 70 deg N, 19 deg E are calculated from EISCAT field-aligned measurements. The procedure used to analyze these data is described and it is noted that full allowance is made for convolution effects in order to obtain accurate mean diurnal variations for summer, winter, and equinox. It is found that, in all seasons, the equatorward wind varies almost linearly from about -80 m/s at 13:00 LT to 170 m/s at 23:00 LT. Also, an overall equatorward shift occurs in the summer of about 30 m/s near noon and midnight, decreasing to 10 m/s near 6:00 and 18:00. On about half the nights in the summer there is a large surge which increases the equatorwind from about 120 m/s at 21:00 to 260 m/s at 22:00 LT. Independent calculations were made at heights of 250, 350, and 450 km and results are examined to detect any departures from current ionospheric parameters. Methods to obtain agreement between these three sets are discussed.
