Project Title: Ozone layer
Problem Definition: The ozone layer refers to the ozone within the stratosphere, which is variations in temperature and pressure divide the earths atmosphere into layers and is thirty miles from the earth sitting at the very top. This is where over ninety percent of the earths ozone resides. The ozone is an irritating, corrosive, colorless, gas with a smell like burning electrical wiring. Each molecule of the ozone layer has three oxygen atoms and is created when oxygen molecules are broken up by energetic electrons.
UV-B radiation (280- to 315- nanometer (nm) wavelength) from the Sun is partially absorbed in this layer. As a result, the amount of UV-B reaching Earth’s surface is greatly reduced. UV-A (315- to 400-nm wavelength) and other solar radiation are not strongly absorbed by the ozone layer. Human exposure to UV-B increases the risk of skin cancer, cataracts, and a suppressed immune system. UV-B exposure can also damage terrestrial plant life, single cell organisms, and aquatic ecosystems.
Problem Solution: to solve the problem with UV-B radiation we will reduce the levels of sulfur dioxide by 25%. With the levels being reduced, the UV-B radiation should decrease and lowering the chances of humans of getting skin cancer and plant damage.
Progress up to date: We have finished up the rest of our research. Now we are in the process of starting to write pour program using Netlogo.
Expected results: We expect to be at least half way finished with the programming by the end January.
