Dust diffusion in upper atmosphere
WebIntroduction. It is believed that, over billions of years, Mars has lost water through atmospheric escape. A classic Martian water loss mechanism is that H 2 molecules that are chemically produced from water vapor in the lower atmosphere diffuse into the upper atmosphere, and their subsequent dissociation results in hydrogen escape 1.As the time … WebNov 7, 2024 · The mesosphere extends from the stratopause (the upper boundary of the stratosphere) to about 85 kilometers (53 miles) above the surface of the Earth. Here, temperatures again begin to fall. The mesosphere has the coldest temperatures in the atmosphere, dipping as low as -120 degrees Celsius (-184 degrees Fahrenheit or 153 …
