Project global sea level rise driven by global-mean-temperature change. Each component contributing to climate-driven sea level rise (thermal expansion, glaciers, the Greenland and the Antarctic ice sheets) is represented by indivdual functions and calibrated separately. Total sea level rise is the sum of the components.
v.2.0.0: code as used for Mengel et al., Nature Communications 2017, forthcoming.
v 1.0.0: code as used for Mengel et al., PNAS 2016, https://dx.doi.org/10.1073/pnas.1500515113.
If you make use of this code, please cite the respective paper.
See the examples/projections.ipynb for projections using a sample global temperature mean timeseries. If you do not have jupyter notebook, install it or look at do_projections.py.
See do_calibration.py. Model calibration is based on data for past thermal expansion, glaciers and ice caps loss and ice sheet evolution, which is not completely openly available. Please contact M. Mengel or the authors of the datasets applied for calibration if you plan to recalibrate or extend the model. The Antarctic ice sheet contribution following Deconto & Pollard 2016, as introduced in v.2.0.0 is not calibrated within this code, but in the fast_ant_sid package.
git clone https://github.com/matthiasmengel/sealevel.git
cd sealevel
then with pip
pip install requirements.txt
or with conda
conda env create -f environment.yml
The model is written in python. If this is new to you, you may have a look at anaconda python. The code has not been tested for Windows. Adaptations to file path definitions would be needed.
scipy, numpy, dimarray, pandas matplotlib for plotting, jupyter for convenience.
See requirements.txt for details.
Please post issues on the issue tracker or contact the author. Contributions or propositions to extend the model are most welcome.
