Welcome to the NSF Polar UV Monitoring Network Web Site!

The National Science Foundation (NSF) Ultraviolet (UV) Monitoring Network was established in 1987 by the NSF Division of Polar Programs in response to serious ozone depletion reported in Antarctica. Biospherical Instruments installed the first instruments in 1988 and has operated the network since then. The network is providing data to researchers studying the effects of ozone depletion on terrestrial and marine biological systems. Network data is also used for the validation of satellite observations and for the verification of models describing the transfer of radiation through the atmosphere.
