This dataset contains PISM simulation results of the Antarctic Ice Sheet based on code release v1.0-paleo-ensemble ( PISM is the open-source Parallel Ice Sheet Model developed mainly at UAF, USA and PIK, Germany. See documentation in
With the help of the added jupyter notebook (Python 2.7.3), all figures can be reproduced as published in the article:
- Albrecht et al., 2020, doi:10.5194/tc-14-633-2020.
Find PISM results as netCDF data. See '' for a list of all performed experiment.
All forcing input data for the experiments and plots can be downloaded and remapped via Some of the original input data files are freely available, for others please contact the author or the corresponding data publisher.
The jupyter notebook ( paleo_paper2_final.ipynb (based on python) in 'plot_scripts' accesses the uploaded PISM results in 'model_data' or 'supplement' and saves the plots as vector and pixel graphics to 'final_figures'. Edit header for changing work paths. Jupyter notebook can be run in the browser and shared, see
The scoring scheme with respect to modern and paleo data based on Python 2.7.3 can be downloaded from ( The ensemble analysis calculates misfits to the paleo constraint database AntICEdat (Briggs & Tarasov, 2013) and to RAISED Consortium (2014) as well as to modern ice geometry from Bedmap2 (Fretwell et al., 2013), ice speed (Rignot et al., 2011) an GPS (Whitehouse et al., 2011). The analysis is based on Pollard et al., (2016) and Briggs et al., (2014).
