Sequential assimilation of multi-mission dynamical topography into a global finite-element ocean model

This study focuses on an estimation of ocean circulation via assimilationof satellite measurements of dynamical ocean topography(DOT) into the global finite-element ocean model (FEOM).The DOT data are derived from a complex analysis of multimissionaltimetry data combined with a referenced earth geoid.The goal of this work is exploring the feasibility of assimilationof the global altimetric signal based on sequential assimilationtechnique. Two different sequential assimilation techniques wereimplemented.
