Editing Mesosphere (section)

==Temperature==
Within the mesosphere, [[temperature]] decreases with increasing [[height]]. This is a result of decreasing absorption of solar radiation by the rarefied atmosphere having a [[Ozone–oxygen_cycle#Mesosphere|diminishing relative ozone concentration]] as altitude increases (ozone being the main absorber in the UV wavelengths that survived absorption by the thermosphere).<ref name="Photochemistry of Ozone">[https://slideplayer.com/slide/10904550/ Photochemistry of Ozone]</ref> Additionally, this is also a result of increasing cooling by [[Carbon dioxide|CO<sub>2</sub>]] [[radiative emission]]. The top of the mesosphere, called the [[mesopause]], is the coldest part of Earth's atmosphere.<ref>{{GoldBookRef|title=mesosphere|file=M03855}}</ref> Temperatures in the upper mesosphere fall as low as about {{convert|-100|C|K F|sigfig=3}},<ref>{{Citation|title=Mesosphere (Wayback Machine Archive)|url=http://www.ace.mmu.ac.uk/eae/atmosphere/older/mesosphere.html|access-date=14 November 2011|publisher=Atmosphere, Climate & Environment Information ProgGFKDamme (UK [[Department for Environment, Food and Rural Affairs]])|url-status=dead|archive-url=https://web.archive.org/web/20100701030705/http://www.ace.mmu.ac.uk/eae/atmosphere/older/mesosphere.html|archive-date=1 July 2010}}</ref> varying according to [[latitude]] and [[season]].
