Description

The Mesosphere is characterised by falling temperature with height - temperatures fall to -100°C. Thin clouds comprised of ice crystals, Noctilucent Clouds, sometimes occur at higher latitudes in the higher part of the Mesosphere at approximately 80km in altitude.

The boundary between the Stratosphere and the Mesosphere is known as the Stratopause.
