Abstract
The temperature structure in the 80- to 105-km region exhibited strong variability due to the influence of gravity waves, tides, and sporadic Na layers (Nas). Extreme temperatures of 140 K and 255 K at 90 km were observed. A cooling rate of 8K/month was exhibited from winter to summer at 85-90 km, and in late May and early June a well-defined cold mesopause formed near 85 km with temperatures typically between 150 and 165 K. This mesopause structure produced an associated enhancement in the Brunt-Vaisala frequency near 90 km. -from Authors
