A visible spectrometer dedicated to ozone and NO 2 monitoring for the next few years has been installed at the French Antarctica base of Dumont d'Urville at 66°S, 140°E. The first three months of data in Austral summer and fall allow the observation of the NO 2 seasonal decay together with its diurnal variation. The data are found incompatible with the currently accepted NO X photochemistry. A conversion of nitrogen compounds into another storage species is required. The reaction which probably involves N 2 O 5 should be active at temperature as high as ‐ 45°C.
