Rough clear sky estimates. Wavelengths: UVA λ=360 nm, UVB λ=300 nm. Source: CICARMA, Emanuela, et al. Sun and sun beds: inducers of vitamin D and skin cancer. Anticancer research, 2009, 29.9: 3495-3500.

Both UVA and UVB cause skin damage (sunburn, premature aging, skin cancer).
UVB is responsible for delayed tanning and burning.
UVA is responsible for the immediate tanning effect.
Exposure to UVB radiation helps the skin produce vitamin D (D3).
