| Summary: | Tangent linear and adjoint models (TAMs) are efficient tools to analyse and
to control dynamical systems such as NEMO. They can be involved in a large
range of applications such as sensitivity analysis, parameter estimation or the
computation of characteristic vectors. A TAM is also required by the 4D-Var
algorithm, which is one of the major methods in data assimilation. This paper
describes the development and the validation of the tangent linear and
adjoint model for the NEMO ocean modelling platform (NEMOTAM). The diagnostic
tools that are available alongside NEMOTAM are detailed and discussed, and
several applications are also presented. |
