SUPERSEDED: ACCESS-CM2 model output for control simulation for partially coupled experiments

Updated: 2024-11-01

This dataset collection comprises output from the ACCESS-CM2 model for tropical partially coupled (or pacemaker-style) experiments. In this project, the ACCESS-CM2 is used to conduct simulations in which sea surface temperatures (SSTs) in the tropical Indian and Pacific Ocean basins are restored to a 12-month repeating climatology derived from a pre-industrial control (piControl) simulation. These experiments are designed to quantify the relative impacts of suppressing interannual SST variations in individual tropical ocean basins (Indian or Pacific) and in the combined Indo-Pacific region. The collection includes four experiments: Control run (CTRL): a baseline fully coupled piControl run Indian Ocean climatology (IO_clim_mod): SSTs in the tropical Indian basin restored to CTRL climatology Pacific Ocean climatology (PO_clim_mod): SSTs in the tropical Pacific basin restored to CTRL climatology Indo-Pacific climatology (IPO_clim_mod): SSTs across both the tropical Pacific and Indian basins restored to CTRL climatology This dataset comprises output from the ACCESS-CM2 model for a fully coupled pre-industrial control (piControl) experiment. This experiment was run to construct a sea-surface temperature climatology for associated partially coupled (pacemaker-style) experiments and to provide a baseline for comparison with these experiments. It was branched from year 950 of the CMIP6 piControl and run on the NCI supercomputer Gadi using Broadwell processors. The output was post-processed using the ACCESS-MOPPeR tool (https://doi.org/10.5281/zenodo.10346217) following wherever possible the CMIP6 conventions. This dataset was decommissioned in 2024 when the experiment was re-published as part of CMIP6Plus: https://geonetwork.nci.org.au/geonetwork/srv/eng/catalog.search#/metadata/f5834_4005_0679_5821
