ACCESS model outputs for FW simulations under PI and LIG boundary conditions
Data files
Abstract
The modelling dataset presented here corresponds to the manuscript entitled "Australasian hydroclimate response to the collapse of the Atlantic Meridional Overturning Circulation under pre-industrial and Last Interglacial climates".
Over the last 50 years, the AMOC has weakened and is projected to weaken further or even collapse this century due to freshwater influx from melting glaciers and ice sheets, under climate warming driven by rising greenhouse gas concentrations. Despite numerous modelling studies investigating the climatic impacts of an AMOC shutdown, little is known about its impact on Australasian hydroclimate, particularly under climatic conditions warmer than the pre-industrial (PI). Here, using the ACCESS-ESM1.5 model, we assess the processes impacting seasonal hydroclimate in the Australasian region in response to an AMOC shutdown under PI and Last Interglacial (LIG) climatic background conditions.

The data files pi.nc, pifw.nc, lig.nc, ligfw.nc contains monthly mean values to recreate all the plots in the manuscript.
Code/Software
All the final data is in .nc or netcdf format, which can be opened and read by free/open software applications such as Panoply, HDFview, ferret, NCO (ncview) and Python.
Description of the data and file structure
The data files are in netcdf format. Below is the description for all the variables. The units are provided in brackets.
amocts: Atlantic Meridional Overturning Circulation time series (Sv)
uwind: surface zonal wind (m/s)
vwind: surface meridional wind (m/s)
sat: surface air temperature (K)
precip: precipitation (kg m-2 s-1)
psl: mean sea level pressure (Pa)
zg: geopotential height (m)
evap: evaporation (kg m-2 s-1)
sice: sea ice (fractional values).
Sharing/Access information
Data was derived from the model outputs of simulations present at the National Computational Infrastructure. The model code is available at https://access-hive.org.au/models/run-a-model/run-access-esm/#prerequisites
Methods
This data is generated by peforming numerical simulations with the Australian Community Climate and Earth System Simulator Earth System Model Version 1.5 climate model. It was processed using software such as national climate operator (NCO), climate data operator (CDO), and ferret to generate monthly means of simulations used in this study.
