Model simulation data for climate response to anthropogenic aerosol pattern of 1970s and 2000s

We provide model data from experiments with the coupled atmosphere-ocean climate model MPI-ESM1.2 of Fiedler and Putrasahan (accepted). These are processed data files in netCDF format used for figures shown in the manuscript:

• SST_change_SP-75_minus_PI.nc  - mean difference in sea-surface temperatures associated with the change in the anthropogenic aerosol pattern of 1975 relative to 1850 from 200-years of model output of MPI-ESM1.2 (Figure 1c, Fiedler and Putrasahan, 2021)
• SST_change_SP-05_minus_SP-75.nc - mean difference in sea-surface temperatures associated with the change in the anthropogenic aerosol pattern of 2005 relative to 1975 from 200-years of model output of MPI-ESM1.2 (Figure 1d, Fiedler and Putrasahan, 2021)
• UWIND_change_SP-75-ATF_minus_PI.nc - mean difference in zonal 10m-wind component associated with the  change in the anthropogenic aerosol pattern of 1975 (enhanced anthropogenic aerosol optical depth) relative to 1850 from 200-years of model output of MPI-ESM1.2 (Figure 1e, Fiedler and Putrasahan, 2021) 
• MSLP_change_SP-75-ATF_minus_PI.nc - mean difference in the mean sea-level          pressure associated with the change in the anthropogenic aerosol pattern of 1975 (enhanced anthropogenic aerosol optical depth) relative to 1850 from 200-years of model output of MPI-ESM1.2 (Figure 1f, Fiedler and Putrasahan, 2021) 
• AMOC_*.nc - mean North Atlantic overturning circulation at 1000 m below the sea surface in the (*) experiments with MPI-ESM1.2 (Figure 2a-b, Fiedler and Putrasahan, 2021) 
• NAHT_total_*.nc - mean total northward Atlantic heat transport in the experiments with MPI-ESM1.2 (Figure 2c-e, Fiedler and Putrasahan, 2021) 
• NAHT_gyre_*.nc - gyre component of the mean northward Atlantic heat transport in the experiments with MPI-ESM1.2 (Figure 2c-e, Fiedler and Putrasahan, 2021) 
• NAHT_moc_*.nc - overturning component of the mean northward Atlantic heat transport in the experiments with MPI-ESM1.2 (Figure 2c-e, Fiedler and Putrasahan, 2021)

We further provide primary data information in Fiedler_Putrasahan_primary-data-information.txt.

The model simulations were performed and analysed on the high-performance computer mistral of DKRZ. Our research was largely funded by the Max-Planck-Institute for Meteorology. Refer to Fiedler and Putrasahan (2021) for further information on the data and interpretation of the results.
