´AbstractAbstract Three NILU-UV multichannel radiometers have been installed in 1999 at the Argen- Argentinian sites of Ushuaia (54S), Marambio (64S) and Belgrano-II (77S) in order to contin- tinian continuously monitor UV radiation, photosynthetically active radiation and total ozone. The uously measurements were established by INM, Spain in collaboration with FMI, Finland, 55 DNA-IAA, Argentina and CADIC, Argentina to observe and characterize the spatial and temporal evolution of ozone and ultraviolet radiation in the Antarctic region. Spe- Special attention has been given to the quality control and quality assurance of the mea- cial measurements under harsh climatological conditions. The ozone and UV time series of surements 2000–2006 were calibrated using a polynomial fit for lamp measurements performed 1010 every second week all year round. The gaps in these data are minimal, with almost no data missing, and the data products are available from http://www.polarvortex.orghttp://www.polarvortex.org in near real time. The data products include the erythemally-weighted UV, UVB and UVA radiation, photosynthetically active radiation (PAR), total ozone (O3) and a cloud parameter (CLT). For UV data, dose rates as well as daily doses are available; from 15 parameter (CLT). For UV data, dose rates as well as daily doses are available; from 15 3) and a cloud parameter (CLT). For UV data, dose rates as well as daily doses are available; from 1515 these the maximum measured UV indices (UVI), during 2000–2006, were 12.0, 9.7 and 8.1 at Ushuaia, Marambio and Belgrano-II, respectively.
