Description:

El Niño/Southern Oscillation (ENSO) has far reaching global climatic impacts and so extending useful ENSO forecasts would have great societal bene ﬁt. However, one key variable that has yet to be fully exploited within coupled forecast systems is accurate estimation of near ‐surface ocean salinity. Satellite sea surface salinity (SSS), combined with temperature, help to improve the estimates of oceandensity changes and associated near ‐surface mixing. For the ﬁrst time, we assess the impact of satellite SSS observations for improving near ‐surface dynamics within ocean reanalyses and how these initializations impact dynamical ENSO forecasts using NASA's coupled forecast system (GEOS ‐S2S‐2). For all initialization experiments, all available sea level and in situ temperature and salinity observations are assimilated.
