Observations from the NILU-UV Antarctic network since 2000

Abstract

Total 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.
