| Since December 2010, the MyOcean global analysis and forecasting system has consisted of the Mercator Ocean NEMO global 1/4 degrees configuration with a 1/12 degrees nested model over the Atlantic and the Mediterranean. The open boundary data for the nested configuration come from the global 1/4 degrees configuration at 20 degrees S and 80 degrees N. The data are assimilated by means of a reduced-order Kalman filter with a 3-D multivariate modal decomposition of the forecast error. It includes an adaptive-error estimate and a localization algorithm. A 3-D-Var scheme provides a correction for the slowly evolving large-scale biases in temperature and salinity. Altimeter data, satellite sea surface temperature and in situ temperature and salinity vertical... |
