A simple finite difference‐based approximation for biogeochemical tangent linear and adjoint models
by Helen Hill for CBIOMES
CBIOMES investigators Paul Mattern and Chris Edwards present a technique that accurately approximates tangent linear and adjoint models for data assimilation applications based only on evaluations of the nonlinear model. The resulting approximation offers a simple way to create readily maintained tangent linear and adjoint model code as only major changes to the nonlinear model formulation necessitate modifications of the tangent linear or adjoint model code.
