mesopause
mesopause The upper boundary of the mesosphere, 85 km above Earth's surface. Temperatures close to the mesopause are low, typically around -110°C. Temperatures at this level are at their lowest in the summer, and values as low as -162°C have been recorded by rocket-borne instruments flown into noctilucent clouds, whose condensation close to this atmospheric level during the summer months is favoured by such conditions.

mesopause
mesopause In the atmosphere, the inversion at about 80 km height, which separates the mesosphere from the thermosphere above. The first 10 km of the mesopause are almost isothermal. The mesopause is liable to be marked by noctilucent cloud composed of ice crystals on meteoric dust. See also ATMOSPHERIC STRUCTURE.
