Controls on subtropical cloud reflectivity during a waterbelt scenario for the Cryogenian glaciations - Dataset and analysis scripts

The dataset contains - 2d data for all global simulations and 3d data for selected global simulations; zonal-mean and global-mean monthly-mean and climatological data (format: netcdf) - 2d data, cross sections and vertical profiles for ICON-NWP model hierarchy - initial and boundary conditions (format: netcdf) or the scripts to obtain initial and boundary conditions from conducted simulations - runscripts (located in the subdirectories corresponding to each model) The data is organized in 9 subdirectories. 4 subdirectories contain the simulation output data corresponding to the 4 models CAM, ICON-AES, ICON-NWP, and ICON-LEM.

We describe how we obtained and modified the models in the files “CAM_description”, “ICON-AES_description”, and “ICON-NWP_description”. We also provide the runscripts for the conducted simulations. One subdirectory contains the grids required for the simulations as well as the files to create the limited area grids using the grid generator provided by the DWD ICON-TOOLS 2.3.3. 4 sudirectories contain the initial and boundary conditions as well as the remapping scripts to obtain the initial and boundary conditions for the ICON-NWP/-LEM model hierarchy.

The latter is described in the file “Create_initial_and_boundary_conditions_ICON-NWP_and_ICON-LEM”. Postprocessing of the simulation output data was performed using the Climate Data Operator software provided by DKRZ. B) Analysis scripts The analysis scripts are located in the subdirectory “analysis_scripts”.

The directory "analysis" contains intermediate results generated by the analysis scripts and the directory "figures" contains the figures generated by the analysis scripts. To run the analysis scripts we applied the Kernel „Python 3“ as provided by the German Climate Computing Center (DKRZ).
