Frequently Asked Questions
No, it is a very low-frequency, highly technical term specific to atmospheric science.
It would be highly unusual and likely misunderstood, as it refers to a very specific scientific concept.
It is the region where short-wave solar radiation (like ultraviolet light) breaks apart molecules, initiating important chemical reaction chains.
No, the ozone layer is primarily in the stratosphere. The chemosphere is higher, encompassing parts of the mesosphere and thermosphere, though some ozone-related chemistry occurs there.
The region of the Earth's atmosphere, between about 40 and 90 km altitude, where chemical reactions involving short-wave solar radiation are significant.
