Re: UV flux at Earth's surface

["Björn Cedervall" <bjorn_cedervall@hotmail.com>]

I don't know about trends but there is a good overview (calculated) that 
was published in Photochemistry and Photobiology, approximately 1976 
(+/- 1 year). This article gives the flux according to wave length and 
latitude. The article also discussed cloud effects. I probably still 
have it (slight archeological excavation in the attic...).
