Data Center Description
The EPA UV-Net Program operates and maintains a network of Brewer spectrophotometers throughout the United States which measure full-sky spectrally resolved solar radiation in the UV-B and UV-A bands. Irradiance and total column ozone concentrations are derived from the data. The data are analyzed and stored in a data base for dissemination to government and non-government scientists and interested parties.
Fourteen of the UV monitoring sites are located in National Parks and are operated by National Park Service employees as part of the Park Research and Intensive Monitoring of Ecosystems Network. An additional set of seven sites are currently operating in urban areas. Ultraviolet solar radiation is measured with a Brewer Mark IV, single-monochrometer, spectrophotometer manufactured by Kipp and Zonen of Saskatoon, Saskatchewan, Canada. The UV monitoring under this program is coordinated with measurement programs of other U.S. Federal agencies through the U.S. Global Change Research Program.
