Summary

Measurements of spectral ultraviolet irradiance require spectroradiometers with high resolution and stability, and well known behavior of the instrument. A UV-spectrophotometer is described and methods of calibrations are shown. A set of measurements in the Utah Rocky Mountains (Snowbird-Hidden Peak, in 3300 m elevation) compared to those at the Wasatch Front (Logan, 1400 m) is discussed. Several sets of measurements are used to show the effect of solar zenith angle, elevation and cloudcover on direct solar and diffuse irradiance.
