Póster elaborado para la SCAR Open Science Conference celebrada en Auckland, Nueva Zelanda los días 25-28 de agosto de 2014Total ozone and UV measurements have been performed with the NILU-UV radiometer at the station of Ushuaia (54◦S), Marambio (64◦S) and Belgrano II (77◦S) since 2000. The network was
established in 1999/2000 by the Spanish Agencia Estatal de Meteorología (AEMET) in collaboration with the innishMeteorological Institute (FMI), the Argentinian Dirección Nacional del Antártico-Instituto Antártico (DNA-IAA) and Centro Austral de Investigaciones Cientificas (CADIC). The location of the network was chosen
in order to monitor total ozone and UV radiation at different sides of the polar vortex: Belgrano II is mostly located inside the vortex, Marambio at various times inside, on the edge of, or outside
the vortex, while Ushuaia is mostly outside the vortex.The MAR Project was financed by the National R+D Plan of the Spanish Ministry of Science and Technology (National Research Program in the Antarctic) under contract REN2000-0245-C02-01
