This bulletin gives an estimate of the accuracy of MERCATOR OCEAN’s analyses and forecast
for the season of April-May-June 2014. 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), the Atlantic and Mediterranean zoom at 1/12° (PSY2), and the
Iberia-Biscay-Ireland (IBI36, upgraded in April 2014) monitoring and forecasting systems
currently producing daily 3D temperature, salinity and current products. Surface Chlorophyll
concentrations from the BIOMER biogeochemical monitoring and forecasting system are also
displayed and compared with simultaneous observations.
