This bulletin gives an estimate of the accuracy of MERCATOR OCEAN’s analyses and forecast for the season of April-May-June 2011. It also provides a summary of useful information on the context of the production for this period. Diagnostics will be displayed for the global 1/12° (PSY4), global ¼° (PSY3) and the Atlantic and Mediterranean zoom at 1/12° (PSY2) monitoring and forecasting systems currently producing daily 3D temperature salinity and current products. An update of PSY2 is introduced that corrects salinity problems in the North East Atlantic. This new version of PSY2 starts to deliver operational products in July 2011.
