The BREWER Spectrophotometer consists of a weatherproof spectrophotometer, azimuth tracker and stand. It provides near simultaneous observations of the total ozone column, SO2, and UV spectra.
The two-axis tracking, appropriate filter selections, on-board wavelength calibration and data logging are managed through internal electronics and an IBM compatible host computer. Control software for the PC enables 24 hr scheduling and remote unattended operation.
Ultraviolet (UV) radiation has been linked to skin cancer, skin aging, cataracts, and immune system suppression in humans and animals. In plants, enhanced UV radiation exposure has lead to crop damage and reduced yields.
From the point of view of risk assessment, exposure to UV radiation represents a large potential hazard. Although the necessity of UV monitoring is clear, the nature of the radiation and our sensitivity to it pose data collection challenges. If left un-addressed these challenges could leave our under-standing of future UV trends and impacts uncertain.
