On page 253, we correctly state that a UVI of 10 corresponds to 0.25 W m−2 erythemally weighted UV radiation. But the equations in the preceding lines have the multipliers interchanged. The equations should be:
UVI = 40 × UVEry (for UVEry in W m−2)
UVI = 0.4 × UVEry (for UVEry in μW cm−2)
Taking this into account, the equation on page 254 also changes, and should be:
UVB280–315nm (W m−2) = 0.189 × UVI (i.e. not 18.9 × UVI)
