NOAA Antarctic UV Monitoring Network

Antarctic Ultraviolet (UV) Monitoring Network was established in 1987 by the National Science Foundation (NSF) Division of Polar Programs in response to serious ozone depletion reported in Antarctica. Biospherical Instruments (BSI) installed the first instruments in 1988 and operated the network until 2009*. NSF transitioned operation of the Antarctic UV Network to NOAA/ESRL/GMD in 2010.

This network provides data to researchers studying the effects of ozone depletion on terrestrial and marine biological systems, ozone hole monitoring, validation of satellite observations, and verification of atmospheric radiation transfer models. The network consists of three stations: South Pole Station, McMurdo Station, and Palmer Station. Each station is equipped with a BSI SUV-100 Spectroradiometer, a GUV Multi-Channel Radiometer, an Eppley PSP Pyranometer, and an Eppley Total UV (TUVR) Radiometer. Data are collected every 15 minutes and processed into daily UV products.
