Atomic oxygen, which is essential to the formation of ozone, is made in the upper atmosphere and then transported downward, where it is eventually converted to ozone.
Volcanic activity is one of the major influences on the earth's atmosphere.
These waves re-distribute solar energy and energy associated with weather systems, throughout the entire earth's atmosphere, which stretches from the ground to over 100 km. These measurements also tell us much about the controlling processes for ozone. The combination of spatial and temporal observations, provided by satellite and ground-based systems, is very effective and powerful. Many of these waves and processes have dimensions which are hemispheric or global.
