This set of holdings provides access to surface marine meteorological weather reports and observations made by merchant
and naval ships, drifting buoys and other platforms and vessels over
the global ocean. Data have been collated and harmonised and quality control checks have been performed, but no attempt
has been made to assess or correct for potential biases.
Data are provided for a range of commonly observed variables.

An eddy-permitting ocean reanalysis spanning the period 1979–2012. Includes increased horizontal and vertical resolution, an prognostic sea-ice component, new versions of the ocean and data assimilation system, revised surface fluxes, new version and treatment of satellite sea surface height data, and assimilation of sea-ice concentration, among others.

calendar_today Interval/period: N/A

Uses a sophisticated data assimilation methodology which includes a model bias correction. The ocean model used is forced by atmospheric daily surface fluxes, relaxed to SST and bias corrected.
