Diffusion model with Data Assimilation of observed SF6 concentrations using Green’s Functions was applied to concentrations hindcasts estimating the movement of water mass released SF6. The SF6 concentrations were hindcasted with the currents and the released concentration flux estimated by the assimilation of the observed SF6 concentrations into the model in order to track the dye patch. Sets of hindcast experiments were carried out to evaluate the dye patch trajectories, increasing the observed data for the data assimilation. These experiments suggested that the data assimilative model could provide a good approximation of the trajectory in two days after the data assimilation. The time series of max point of the concentrations and its covariance matrix calculated by this model provided the effective information to estimate the movement.
