arizona: Just moved to Arizona from Michigan and am amazed at the red sunsets and blue skies during the day. In Michigan, the daytime skies were often grayish/white and the sunsets were pale. Does this have to do with pollution or elevation? I'm thinking pollution because I can see more stars out here too.|||Lack of air pollution|||Strangely enough, pollution will make sunsets even more red and the sky grayer. The feature that you describe in Arizona is most likely due to the geography. The mostly flat unobstructed land mass appear to make the sun appear farther away and thus increase scattering making sunsets redder. You see more common red sunsets on the west coast beaches too compared to unleveled areas in california.|||my teacher said the pollution but i doubt it.|||Often in the desert the dry dust in the air makes the sunsets red. I don't know why the skies are so blue, but i noticed it also. Perhaps lack of constant cloud cover out in the desert.|||A girl from Connecticut said the same thing when she came to Michigan. The skies are not blue and the sunsets are ugly. I don't think it is pollution though, considering the skies are the same way in the UP where there isn't much pollution at all. Michigan just has ugly weather. :-)|||I live in Phoenix. We learned in school it's the angle of the sun and the amount of dust in the air. Makes you appreciate all the dirt around here. Not the pollution.
