This process is the only way to ensure that the system can capture a maximum amount of sunlight every day. UV light exposure also causes white and dark spots on the skin, as it damages the surface cells. Even though geothermal might have more availability, there are no odors or sounds that people find to be bothersome with this installation. People working in a hot environment are at risk of heat exhaustion. This information is useful in meteorology, science, agriculture, tourism, and other fields. There are a number of charts that can be used for smaller installations that give the average insolation over a period of years, but utility scale installations will use their own surveys conducted over a certain period. In the case of diffuse radiation, though, it reaches the solarimeter after it is scattered by dust, particles in the atmosphere, and gas molecules.
