Adjoint models are increasingly being developed for use in meteorology and oceanography. Typical applications are data assimilation, model tuning, sensitivity analysis, and determination of singularâ€¦ (More)

We first describe the principles and practical considerations behind the computer generation of the adjoint to the Massachusetts Institute of Technology ocean general circulation model (GCM) using R.â€¦ (More)

FastOptâ€™s new automatic differentiation tool TAF is applied to the two-dimensional Navier-Stokes solver NSC2KE. For a configuration that simulates the Euler flow around a NACA airfoil, TAF hasâ€¦ (More)

A structurally highly simplified, globally integrated coupled climate-economic costs model SIAM (Structural Integrated Assessment Model) is used to compute optimal paths of global CO2 emissions thatâ€¦ (More)

We describe computational aspects of automatic differentiation applied to global ocean circulation modeling and state estimation. The task of minimizing a cost function measuring the ocean simulationâ€¦ (More)

TM2 is a global three-dimensional model of the atmospheric t ransport of passive tracers. The adjoint of TM2 is a model that allows the efficient evaluation of derivatives of the simulated tracerâ€¦ (More)

Models of atmospheric transport can be used to interpret spa tiotemporal differences in the observed concentrations of CO 2 in terms of its surface exchange fluxes. Inversion of the atmosphericâ€¦ (More)
