Paper Introduction:
SOLAR RADIATION AND THE ATMOSPHERE
As the earth's nearest star, the sun determines much of what happens on the earth--its energy is what allows continued life on the earth, and its actions create the earth's weather, in the form of wind, clouds, and other climatic examples. The sun's warmth and energy are so important that without them the earth would become encased in ice (1:74). However, the earth is not completely open to solar radiation. The different layers of the earth's atmosphere provide different interactions (and different results from those interactions) with solar radiation.
The earth's atmosphere, the receiving end of the sun's radiation, is divided into four parts: the troposphere, which is the bottom-most layer and extends from the earth's surface to about 11 kilometers high (at which point the stratosphere
