Dual number-based variational data assimilation: Constructing exact tangent linear and adjoint code from nonlinear model evaluations
Dual numbers allow for automatic, exact evaluation of the numerical derivative of high-dimensional functions at an arbitrary point with minimal coding effort. We use dual numbers to construct tangent linear and adjoint model code for a biogeochemical ocean model and apply it to a variational (4D-Var...
