Yeah, TOMS is a good mission, though I must say there's a misstatement on that page I cringe at. The part where it says that UV-B is 290-320 wavelengths is just flat wrong. In fact, it's ultraviolet light with a wavelength of 290 to 320 nanometers. Each photon has only one wavelength, not hundreds of them.
