This bulletin gives an estimate of the accuracy of MERCATOR OCEAN’s analyses and forecast
for the season of January-February-March 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 (IBI) 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. Finally, a spurious eddy which
appears in March 2014 near the coasts of Portugal in PSY4 and PSY2 is described and
analysed.
