A Jupyter notebook demonstrates how to download, read, and plot the time series for the Global Mean Sea Level (GMSL) trend generated from the Integrated Multi-Mission Ocean Altimeter Data for Climate Research Version 5 (https://doi.org/10.5067/GMSLM-TJ150). The notebook concludes by writing the time series to a CF-compliant netCDF4 file.
