ACCESS1-3 model output prepared for CMIP5 historicalNat (Version 2015)

Updated: 2019-05-17

ACCESS1-3 model output prepared for CMIP5 (Coupled Model Intercomparison Project phase 5) of the historical, natural forcing (historicalNat) experiment. Ensembles included r1i1p1, r2i1p1 and r3i1p1. ACCESS1-3 is a general circulation climate model developed as a collaboration between CSIRO and BoM. This simulation is a historicalNat experiment, simulating the global climate between 1850-2020, using historical natural forcing (e.g., volcanoes and solar variability) as the only forcing. The ARC Centre of Excellence for Climate System Science (ARCCSS) has run this particular experiment. This model simulation is part of the contribution of the Australian Community Climate and Earth System Simulator Coupled Model (ACCESS-CM) to CMIP5. There are two versions of the ACCESS-CM, namely ACCESS1.0 and ACCESS1.3. ACCESS1.3 uses these components: the UK MetOffice UM atmosphere model, the GFDL MOM4p1 ocean model, the LANL CICE4.1 sea-ice model and the CABLE land surface model. The historicalNat experiment is a long-term simulation of the 20th century climate including as forcing only natural forcing. The simulation covers from 1850 to 2005 and branches from the pre-industrial control (piControl) experiment depending on the ensemble. An extension of the simulation from 2006-2020 was added later. The ensemble member is defined by a triad of integers describing a specific initial condition (r), initialisation method (i), and perturbed physics version (p). These are valid only in the contest of a specific model. historicalNat is an experiment of the CMIP5 - Coupled Model Intercomparison Project Phase 5 (https://pcmdi.llnl.gov/mips/cmip5/). CMIP5 is meant to provide a framework for coordinated climate change experiments for the next five years and thus includes simulations for assessment in the AR5 as well as others that extend beyond the AR5. 7.1 historicalNat (7.1 natural-only historical simulation) - Version 1: Historical simulation but with natural forcing only.
