- n. The portion of the atmosphere from about 30 to 80 kilometers (20 to 50 miles) above the earth's surface, characterized by temperatures that decrease from 10°C to -90°C (50°F to -130°F) with increasing altitude.

- n. the atmospheric layer between the stratosphere and the thermosphere
So it seems there are already fine particles that are levitated up to what we call the mesosphere, about 100 kilometers up -- that already have this effect.
At the top of the mesosphere is another transition zone known as the mesopause.
University of Calgary climate scientist and geoengineering expert David Keith has suggested that we might ultimately find a particle that can be placed still higher up in the atmosphere, in the region called the mesosphere, above the ozone layer, where it would cause fewer problems.
The next layer, above the stratosphere is the mesosphere, which is colder than the stratosphere, then we could think that the heat pipe system restarted there; however, the gaseous mass in the mesosphere is lower than the gaseous mass of the stratosphere, so we cannot infer a restoration of the heat pipe system in the mesosphere.
Guy made a habit of puncturing the mesosphere with his soaring punts.
Above the earth were the layers of the atmosphere—troposphere, stratosphere, mesosphere, thermosphere—and above those was the void of space.
This type of ultraviolet light is called “Extreme UV” and is only available in the mesosphere, which begins about 50 kilometers (160,000 ft) above sea level.
Instantaneously, if the carbon dust combusted simultaneously; or slowly, if it took weeks for the rarified oxygen in the mesosphere to be replenished.
The snow covered mountaintops turned a pale blood red as they reflected the light from the slow burning mesosphere.
Properly dispersed in the mesosphere, 1,000 pounds of Carbon Deoxidizer is enough to remove approximately two billion tons of carbon dioxide gas from the atmosphere before the Carbon Deoxidizer molecules are themselves destroyed by cosmic ray spallation.
