Dual number-based variational data assimilation: Constructing exact tangent linear and adjoint code from nonlinear model evaluations

© 2019 Mattern et al. Dual numbers allow for automatic, exact evaluation of the numerical derivative of highdimensional 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...
