Code and data for Keizer et al. (2023): "The acceleration of sea-level rise along the coast of the Netherlands started in the 1960s"
Use local tide gauges and atmospheric reanalyses to study the evolution of the rate of sea level rise over time.
This is the code supporting Keizer et al. 2023, submitted to Ocean Science. This repository can be cited using https://doi.org/10.5281/zenodo.7994728.
The analysis is organised in three steps:
- Two Notebooks (prepare_atmospheric_data.ipynb, obtain_pressure_gradient.ipynb) explain how to download the input data, preprocess the data and export intermediate csv files to /data_atmosphere
- gam_model.ipynb performs the statistical modeling and exports the results as csv files to /outputs
- The final figures and tables are made in make_figures.ipynb and make_tables.ipynb, respectively. Figures are exported to /figures and tables are written out as latex format that is copy/pasted directly into the manuscript.
The analysis of sea surface temperature and sea level for the appendix of the manuscript is in the notebook wind-driven-sea-level_sst_analysis.ipynb.
There are 2 conda environment.yml files (because the two spectral packages mtpec and spectrum don't seem to want to be installed at the same time):
environment_NLSL.yml: used for almost all codeenvironment_NLSL_mtspec.yml: used forfigures_MV.ipynb
- tide gauge data (PSMSL)
- reanalysis for wind (20CR, ERA5)
- SST data (COBESST)
