2 paź 2019 · Mesosphere. Located between about 50 and 80 kilometers (31 and 50 miles) above Earth’s surface, the mesosphere gets progressively colder with altitude. In fact, the top of this layer is the coldest place found within the Earth system, with an average temperature of about minus 85 degrees Celsius (minus 120 degrees Fahrenheit).
25 sty 2013 · Aeronomy of Ice in the Mesosphere (AIM) – NASA’s AIM satellite can remotely sense night-shining clouds in the mesosphere. These noctilucent clouds are made of ice crystals that form over the summer poles at an altitude too high and a temperature too cold for water-vapor clouds.
25 sty 2013 · The thermosphere increases in temperature with altitude because the atomic oxygen and nitrogen cannot radiate the heat from this absorption. Mesosphere 31–53 Miles – Studying the mesosphere is essential to understanding long-term changes in the Earth’s atmosphere and how these changes affect climate.
31 paź 2022 · The region of the atmosphere from 48 km to 105 km (30 miles to 65 miles) above the Earth’s surface is called the mesosphere and lower thermosphere or MLT. NASA TIMED/SABER measurements of temperature, geopotential height, & thickness reveal a cooling, contracting mesosphere & lower thermosphere (MLT).

NASA’s heliophysics researches the ionosphere-thermosphere-mesosphere region where our neutral atmosphere transitions into the ionized plasma of space.
