Talk:Solar azimuth angle

From Wikipedia, the free encyclopedia

I added another formula for the azimuth that is popular, and cited by Seinfeld and Pandis in Atmospheric Chemistry and Physics. I also clarified the conventions for azimuth, although I had some difficulty with the wording, so if anyone wants to take a stab at clarifying that please go ahead. I addressed the serious shortcomings of using inverse sine to find the azimuth angle since it is has many solutions, and most calculators and spreadsheets will only return solutions between -90 and 90 degrees. Finally I added a link to the NREL sun position calculator which I think is an excellent standard. --Mikofski 19:45, 22 August 2007 (UTC)
