Aims: The dangerous portion of ultraviolet radiation is widely believed to be completely absorbed by the atmosphere before reaching Earth’s surface. Our objective is to make multiple measurements at Earth’s surface of the solar irradiance spectrum in the range 200-400 nm. Methods: We made numerous measurements of the solar irradiance spectrum in the range 200400 nm at an elevation of 56 m with International Light Technologies ILT950UV Spectral Radiometer mounted on a Meade LXD55 auto guider… Expand
