This bulletin gives an estimate of the accuracy of MERCATOR OCEAN’s analyses and forecast for the season of July-August-September 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. Two new systems are operational since July 2011: IBI on the North East Atlantic at 1/36° horizontal resolution, and BIOMER a global biogeochemical model at 1° horizontal resolution forced with PSY3V3R1.The BIOMER system is introduced in this issue.
