    Observation of O+ (4P-4D0) lines in electron aurora over Svalbard

    , Annales Geophysicae, Vol: 22, Pages: 2805-2817, ISSN: 0992-7689

    This work reports on observations of 0<sup>+</sup> lines in aurora over Svalbard, Norway. The Spectrographic Imaging Facility measures auroral spectra in three wavelength intervals (H<inf>β</inf>, N<sup>+</sup><inf>2</inf> 1N(0,2) and N<sup>+</sup><inf>2</inf> 1N(1,3) . The oxygen ion <sup>4</sup>P-<sup>4</sup>D<sup>0</sup> multiplet (4639-4696 Å) is blended with the N<sup>+</sup><inf>2</inf> 1N(1,3 band. It is found that in electron aurora, the brightness of this multiplet, is on average, about 0. 1 of the N<sup>+</sup><inf>2</inf> 1N(0,2) total brightness. A joint optical and incoherent scatter radar study of an electron aurora event shows that the ratio is enhanced when the ionisation in the upper E-layer (140-190 km) is significant with respect to the E-layer peak below 130 km. Rayed arcs were observed on one such occasion, whereas on other occasions the auroral intensity was below the threshold of the imager. A one-dimensional electron transport model is used to estimate the cross section for production of the multiplet in electron collisions, yielding 0. 18 × 10<sup>-18</sup> cm<sup>2</sup>. © European Geosciences Union 2004.

    It is suggested that the seasonal dependence of interannual variability displayed by observed sea surface temperature (SST) over the north tropical Atlantic primarily reflects the seasonality of the remote forcing associated with the North Atlantic and Southern Oscillations and is controlled by the mean damping time scale of SST anomaly. A stochastic model including a seasonally dependent forcing is used to test this hypothesis against observations. © 2004 American Meteorological Society.
