Polar orbiting satellites enable daily and global coverage of the polar oceans, providing an unique monitoring capability of sea ice dynamics over Arctic and Antarctic. Available Ifremer/CERSAT operational products include Arctic and Antarctic ice concentration, extent, and Arctic sea ice drift. Ifremer/CERSAT hosts a unique database of 20-year winter time series of sea ice data: concentration from SSM/I data, sea ice drift from SSM/I, AMSR-E, QuikSCAT and ASCAT/MetOp data. These time series are ongoing and will continue for long term monitoring using the SSM/Is and MetOps operational sensors. These parameters are used as observations for climate change and also for data assimilation in ocean models.
