摘要：The independent point scheme (IPS) is applied to inverting initial condition with the adjoint method for the
ocean pollutant transport model in this work. As an improvement, the linear Cressman interpolation is
removed and the surface spline interpolation is implemented in the IPS. A series of numerical experiments are
carried out to test and compare the improved IPS. And experiment results show that through applying the
improved IPS, what is further reduced is mean absolute errors between simulation results and observations.
Moreover, the inverted distributions are more smooth, accurate and reasonable. In addition, the application
of improved IPS also reduces the variables that need to be inverted and promotes the computational
efficiency. By these numerical experiment results, it is demonstrated that the combination of improved IPS
and adjoint method can be used for the inversion of initial conditions and parameters estimation more
effectively and reliably.
