Changes in atmospheric ozone have been identified from long-term, ground-based, and satellite observations of column ozone amount over much of the earth's surface, yet there is little data available on the resultant ground level ultraviolet (UV) radiation about which there is so much concern. This is explained in part by the difficulties of making UV measurements in the environment, and the lack of any standard instruments or protocols for such work. Instruments designed for spectral solar UV measurement have been compared under laboratory and field conditions. Results indicate that it is possible to consider different instruments contributing to a single network of UV monitoring sites provided careful attention is given to calibration and operation procedures and to understanding each aspect of the instruments' performance.
