Stratospheric Ozone Depletion tutorial
Increased UV radiation in the lower atmosphere, called the troposphere, can result in increased amounts of photochemical smog. Photochemical smog is already ... of CFC's but because of the slow rate of air mixing between the lower and upper atmosphere it is theorized that stratospheric CFC's will stay at a significant level well ...

Tiny dust-size ash particles thrown into the lower atmosphere will float around for hours or days, causing darkness and cooling directly beneath the ash ... of the air by the abundant water and rain present in the lower atmosphere. However, dust tossed into the dry upper atmosphere, the stratosphere, can remain for weeks to months before they finally ...

CRU Information Sheet no. 2: The Causes of Climatic Change
As the stream of solar energy reaches the Earth's atmosphere, the constituents of the atmosphere – gases and particles, clouds and pollution – interfere with the energy stream, reflecting ... sulphur dioxide, high into the atmosphere. Whereas volcanic debris in the lower atmosphere falls out or is rained out within days, the veil of pollution in the upper atmosphere is above the weather ...

Air
Experienced mountain climbers are aware of how thin the air becomes, and may carry oxygen tanks to assist breathing at high altitudes. Within the lower atmosphere, however, air remains remarkably uniform in composition, as a result of efficient recycling processes and turbulent mixing in the atmosphere ...

NCAR Sun & Space Weather Research: Understanding the Solar Atmosphere
Scientists want to know more about the upper atmosphere, partly to bolster communications networks and help keep satellites on course, and partly to learn how it influences temperature and energy in the lower atmosphere. Researchers capture data on the mesosphere and lower ...

Global Climate Change: Research Explorer - Atmosphere
These processes form the earth’s energy budget—and they are key in determining climate: Sunlight that penetrates the atmosphere heats the earth’s surface. Some of that heat is trapped by the atmosphere, keeping the planet warm. That’s why studying ...
