Observations with a meteor radar, two medium-frequency (MF) radars, and a sodium lidar at ALOMAR at Andenes, Norway (69.3°N, 16.0°E) were used to derive tidal winds and temperatures at altitudes from 72 km to 94 km for a period from June 15 to July 15 during the MaCWAVE/MIDAS summer rocket program in 2002. The longitudinal variations of tidal winds were examined including MF radar winds obtained at Poker Flat, Alaska (65.1°N, 147.5°W). Results show continuity in tidal assessments among the instruments at Andenes, large variability in tidal amplitudes in time and longitude, and an expected phase relationship between winds and temperatures despite the amplitude variability.
