Document Summary

The total amount of energy received at the top of the atmosphere at a given point on earth depends on its latitude. The total solar energy striking earth can be found by multiplying the solar constant (1366) by the cross-sectional area of earth (1. 28x10^14) to get a value of 1. 75 x. The radiation intensity at noon on the equator during the june solstice is 91. 70 because. Because of the tilt of the earth at this time, this causes variations in the intensity of the sunlight that reaches these areas. Nitrogen is by far the most abundant gas in the atmosphere. This is because the surface is much better at absorbing a wide range of solar radiation as compared to the air. Much of the sunlight filters down through the air and to the surface. A great amount of solar radiation makes it to the surface.
