Although UV light contains more energy than visible light, snow is a very good reflector of UV ...

The measured UV albedo values of most natural surfaces are smaller than 10% (Feister et al., 1995; McKenzie
et al., 1996), but for fresh pure snow UV albedos near unity have been reported (Grenfell et al., 1994; Wuttke et
al., 2006).

Good summary, thanks RD. This would explain why skiing is so good for getting a tan, especially under your chin!
