SUV-100 on rooftop 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. Observations were extended to the Arctic and are now part of NSF's Arctic Observing Network. The project is providing data to researchers studying the effects of ozone depletion on terrestrial and marine biological systems. Data are also used for the validation of satellite observations and for the verification of models describing the transfer of radiation through the atmosphere.

Material provided on this website is based upon work supported by the National Science Foundation under Grants OPP-89-22832, OPP-0000373, ARC-0907819, ARC-0856268, and ARC-1203250.
