Spectral irradiance of terrestrial sunlight

Does anyone have approximate values of intensity of natural ultraviolet per
wavelength. I'm trying to work out SPF (sun protection factor) from
measurements of monochromatic protection factor at each wavelength. I've done
the transmission measurements and want to factor is up to closely resemble
solar UV. I apologize if this nonionizing radiation subject does not belong in
this group.
