It does not measure increases in surface UV-B, and certainly has no way of measuring UV-B exposure, which is heavily dependent on human behavioural patterns. I suspect the "6.8%/decade" figure is for ozone depletion, but perhaps I am wrong. Since you posted this figure, I welcome your explanation of its meaning. ...Greig
