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).
Temperature in the Mesosphere. The top of the mesosphere is the coldest part of the atmosphere. It can get down to -90Â° C (-130Â° F) there! As you go higher in the mesosphere, the air gets colder. The air is much thinner (less dense) in the mesosphere than in the stratosphere below. There are fewer air molecules to absorb incoming electromagnetic radiation from the Sun. That includes molecules of ozone, which absorb ultraviolet radiation and heat the stratosphere.
