Marine and terrestrial biogeochemical models are key components of the Earth System Models (ESMs) used to project future environmental changes, but their slow adjustment time also hinders effective use of ESMs because of the enormous computational resources required to integrate them to a pre-industrial equilibrium. Researchers in the UK developed a process based on “sequence acceleration” to accelerate equilibration of state-of-the-art marine biogeochemical models by over an order of magnitude. The technique could be applied in a “black box” fashion to existing models. Even under the challenging spin-up protocols used for Intergovernmental Panel on Climate Change (IPCC) simulations, this algorithm was 5 times faster. According to the researchers preliminary results suggested that terrestrial models could be similarly accelerated, enabling a quantification of major parametric uncertainties in ESMs… read more.
