Quasi-Newton methods for atmospheric chemistry simulations: implementation in UKCA UM vn10.8
... Our adaptation of the QN method uses an “inverse update” approximation (Kvaalen, 1991) instead of the more com- monly used “forward updates” (Broyden, 1965). We demon- strate that the approach improves the convergence ...
