       abstract = "The NASA finite-volume General Circulation Model (fvGCM) is a three-dimensional
         Navier-Stokes solver being used for quasi-operational weather forecasting at NASA/GMAO. We use the
         automatic differentiation tool TAF to generate efficient tangent linear and adjoint versions from
         the Fortran 90 source code of fvGCM's dynamical core. fvGCM's parallelisation capabilities
         based on OpenMP and MPI have been transferred to the tangent linear and adjoint codes. For OpenMP,
         TAF automatically inserts corresponding OpenMP directives in the derivative code. For MPI, TAF
         generates interfaces to hand-written tangent linear and adjoint wrapper routines. TAF also generates
         a scheme that allows the tangent linear and adjoint models to linearise around an external
         trajectory of the model state. The generation procedure is set up in an automated way, allowing
         quick updates of the derivative codes after modifications of fvGCM.",
