0 the layer of gases surrounding the earth at a height of between 15 and 50 kilometres that is not affected by the weather and in which the temperature increases with height:
1 the layer of gases that surrounds the earth from about seven to 30 miles above it
Injection of chlorine into the stratosphere would probably be required for significant volcanic-induced ozone depletion.
The detection of living cells in the stratosphere.
Above the troposphere is the stratosphere which is much more stably stratified.
We recognize of course that our views are highly controversial and will need to be verified by further studies of the microbiology of the stratosphere.
There is no question that volcanic debris and sulfur were injected into the stratosphere.
This assumption requires the aspect ratio to be small, troposphere and 10-3 in the stratosphere.
Volcanic eruptions provide an obvious means by which particles could be ejected through the tropopause into the stratosphere.
Volumes of air from the upper stratosphere collected via balloon-carried cryogenic equipment have been found to trap interplanetary microparticles (1).
