Marine Core Service MyOcean : Second Annual Meeting / April 2011 / Roma Reminder - Objectives for R&D Sea Ice Main objective –Finalize three “new” sea ice products: Sea Ice Main issues –Develop of sea ice temperature, IST, product based on AVHRR. The main error sources are clouds. –Ice berg detection from SAR –Automatic ice/water discrimination from SAR Wind Main objective –Provide spatially and temporally consistent ocean eddy-scale forcing Wind Main issues –Exploit available satellite wind data sources that verifiably provide wind details on the ocean eddy scale, but which are poorly exploited by NWP analyses

Marine Core Service MyOcean : Second Annual Meeting / April 2011 / Roma R&D : main achievements Sea Ice Main achievements are Ice berg product and IST products is ready and implemented in V1 Main Challenge SAR based ice water discrimination is delayed. The algorithm is run in automatic mode every night for a test area in the Fram Strait. Preliminary results show that the method can discriminate ice from open water under various wind and ice edge conditions
