Since 1988 I've measured the sun's ultraviolet from a field in Texas. In this video the 170 days in which the UV-B could be measured at or near solar noon during 2011 are transformed into representative musical notes. Each musical note is accompanied by a 360 degree fisheye image of the sky made when the UV-B was measured. The UV-B that controls the frequency of each note is modulated by the angle of the sun in the sky (highest on 21-22 June), the ozone layer (highest in spring), clouds (mainly summer) and dust (mainly May and summer). CREDITS The UV data were converted to sound by this algorithm: http://musicalgorithms.ewu.edu/algori..., which was developed by Dr. Jonathan Middleton with assistance from Andrew Cobb, Michael Henry, Robert Lyon, and Ian Siemer. The UV measurements and sky photographs were made by Forrest M. Mims III (www.forrestmims.org). More info will be added later.
