Carbon monoxide and dioxide concentrations in the atmosphere

The data sources of the dataset are outputs from CMIP6 simulations. The effect of the Southern Ocean on global climate change is assessed using Earth system model projections following an idealised 1% annual rise in atmospheric CO2. The model simulations run over 150 years and were created using the Earth System Grid Federation at the CMIP6 archive (https://esgf-node.llnl.gov/search/cmip6, World Climate Research Programme, 2021). The reported derived data sets are based on the output of sub-set of CMIP6 models, providing all necessary variables for the diagnostics and analysis published in: Williams, R.G., P. Ceppi, V. Roussenov, A. Katavouta and A. Meijers, 2022. The role of the Southern Ocean in the global climate response to carbon emissions. Philosophical Transactions A, Royal Society, in press. The dataset contains 3 types of variables: (1) Time averaged 2D fields: model mean and standard deviation (STD) of the surface warming, ocean heat uptake and storage, radiative response, climate feedback parameter, ocean carbon uptake and storage, cumulative top of the atmosphere heat uptake with examples for 2 models - GFDL-ESM4 and UKESM1-0-LL; (2) Time series of the Sothern Ocean or globally averaged (or globally integrated) variables for each model together with the model mean and STD: surface warming, ocean heat uptake and storage, radiative forcing and radiative response, ocean carbon uptake and storage; (3) Single values for the Sothern Ocean and planetary physical climate feedback parameter and Transient Climate Response to Emissions (TCRE) together with their components. This dataset was created under project Southern Ocean carbon indices and metrics (SARDINE), NERC Grant reference NE/T010657/1 by scientists from University of Liverpool, National Oceanography Centre (Liverpool), Imperial College London and British Antarctic Survey.
