The mesosphere (/ Ë m É s oÊ s f ÉªÉr /; from Greek mesos middle and sphaira sphere) is the layer of the Earth's atmosphere that is directly above the stratosphere and directly below the mesopause. In the mesosphere, temperature decreases as the altitude increases. The upper boundary of the mesosphere is the mesopause, which can be the coldest naturally occurring place on Earth[citation needed] with temperatures below â143 Â°C (â225 Â°F; 130 K).
The mesopause, at an altitude of 80â90 km (50â56 mi), separates the mesosphere from the thermosphere âthe second-outermost layer of the Earth's atmosphere. This is also around the same altitude as the turbopause, below which different chemical species are well mixed due to turbulent eddies.ithin the mesosphere, temperature decreases with increasing height. This is due to decreasing solar heating and increasing cooling by CO 2 radiative emission. The top of the mesosphere, called the mesopause, is the coldest part of Earth's atmosphere.
