Where can I find solar UV radiation data for Earth's surface?

Does anyone have access to the current data about solar radiation reaching Earth's surface ? The most importaint is the UV range divided into UV-A, UV-B and UV-C. If not, then data from the past few years would also be fine. I need it for research but I cannot find anywhere such information.

I got these via google. "solar radiation spectrum (table)"

Thanks for these, for sure I'll use them, but the point is that I need also the data with wavelength from 100 nm, even if those are very little amounts.
