This bulletin gives an estimate of the accuracy of MERCATOR OCEAN’s analyses and forecast for the season of October-November-December 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. In this last issue for the year 2011, quality syntheses for each of the systems are provided in annex D. The main strengths and weaknesses of all systems are illustrated by diagnostics over the year 2011 (except for BIOMER).
