Wind data from the upper mesosphere over Fort Greely, Alaska, and Thule Air Base, Greenland, are presented. The data were gathered with small meteorological rockets and radar reflective chaff in July 1967. These data show increasing easterly winds with height throughout the mesosphere at high latitudes in summer with maximum speeds up to 92 mps and mean speeds near 50 mps in the 75-80 kilometer region. Diurnal and semidiurnal oscillations are resolved and compared with current theoretical values for atmospheric thermal tides. (Author)
