9 Νοε 2019 · There have been fewer observations of water vapor in the mesosphere. Using ground-based water vapor millimeter-wave spectrometer and satellite measurements, Nedoluha et al. found that H 2 O has been increasing in the lower mesosphere since 2006.

20 Οκτ 2022 · Several physical mechanisms drive changes in water vapor in the mesosphere on interannual and longer timescales. Solar-cycle-induced variations in Lyman-α radiation change the amount of water vapor in the upper mesosphere (Hervig & Siskind, 2006; Nedoluha et al., 2009).
Based on all the mechanisms above, we argue that a long‐term increase or decrease of water vapor in the stratosphere and mesosphere will have fundamental global and regional impacts.
31 Δεκ 2006 · We show results of measurements and compare these with calculations and discuss the chemical and dynamical background of the variation of water vapor in the high latitude mesosphere.
30 Ιουν 2021 · Combined data from three NASA satellites have produced a long-term record that reveals the mesosphere, the layer of the atmosphere 30 to 50 miles above the surface, is cooling and contracting. Scientists have long predicted this effect of human-driven climate change, but it has been difficult to observe the trends over time.
22 Φεβ 2016 · By volume, dry air contains 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.039% carbon dioxide and smaller amounts of various other gases as well as varying amounts of water vapor.
2 Οκτ 2019 · The very scarce water vapor present at the top of the mesosphere forms noctilucent clouds, the highest clouds in Earth’s atmosphere, which can be seen by the naked eye under certain conditions and at certain times of day. Most meteors burn up in this atmospheric layer. Sounding rockets and rocket-powered aircraft can reach the mesosphere.
