This Dataset contains the model output described in the study "Changes in local and global climate feedbacks in the absence of interactive clouds: Southern Ocean-climate interactions in two intermediate-complexity models" by Pfister and Stocker 2020, published in Journal of Climate. The two zip files contain the model output of the two models Bern3D-LPX and LOVECLIM, in folder structures explained below. Bern3D-LPX: The 3 folders contain model simulations tuned to different ECS values (2, 3 and 6 Kelvin). Each folder contains three subfolders corresponding to three simulations: Control, 2xCO2 and 4xCO2. For each simulation, two netcdf model output files are given: a timeseries file for quick overview of various spatially averaged variables (e.g., global mean temperature), and a full output file for local analyses as done in the study. For the main simulations with an ECS of 3 Kelvin, annual mean output is provided for the first 500 years of each simulation. Thereafter, the full output is available only for selected years, which can be read out from the netcdf time dimension or, e.g., the netcdf variable "baseyear". Simulations with an ECS of 2 and 6 Kelvin are only used for Figure 8 and its discussion, therefore their full output file was written with less yearly outputs than the main simulation with ECS=3 Kelvin to reduce data load. LOVECLIM: The 2 folders contain the 2xCO2 and 4xCO2 simulations. No separate Control simulations were made, but the first 1000 years of each simulation are unperturbed and used as a control reference (details in Pfister and Stocker 2020, J.Clim.). The two netcdf files for each simulation correspond to atmospheric variables (atmmmyl_cat.nc) and ocean variables (CLIO3m_cat_CO2_2_regridded.nc). Note that the spatial resolution of the atmosphere and ocean component of LOVECLIM are different. Monthly output is provided for the given variables of the full 2000-year-simulations.
