         three-dimensional variational data assimilation program (3DVAR) by replacing the adjoint model with
         that generated by using the ADG software. A number of techniques are used to reduce the time cost of
         the adjoint model. The main contribution of this work is to demonstrate that the time cost for
         developing the adjoint model is dramatically shortened from two years and half by hand to no more
         than three months by using the ADG software. The experimental results show that the time cost of the
         users’ code is reduced by 34% after optimization.",
