Multivariate data assimilation in support of forecasting of the North Atlantic and Mediterranean

This Jason-1 proposal deals with short-range (days) and medium-range (weeks to months) prediction of ocean dynamical variables (typically, currents and tracers). This is done by assimilation of altimetry and in-situ data and the definition of ad hoc diagnostics. Two major applications to existing forecasting systems are included in the proposal: the Mediterranean Forecasting System Pilot Project (an EU project), and the French Mercator project.
