Regional mass-drive (barystatic) sea-level change trend and uncertainties, from 2003-2016 and 1993-2016.
Barystatic sea-level change (also known as ocean mass change) is driven by the exchange of freshwater between the land and the ocean, such as melting of continental ice from glaciers and ice sheets, and variations in land water storage.
Here, we use a range of estimates for the individual freshwater sources, which are used to compute regional patterns (fingerprints) of barystatic sea-level change.
We then compute the trend (rate of sea-level change), and quantify three types of uncertainties of these regional barystatic sea-level change fields:
1. Intrinsic uncertainty: related to the observational error;
2. Temporal uncertainty: related to the temporal variability in the time series;
3. Spatial-structural: related to the location/distribution of the mass change sources;
The analysis and results published are based on relative sea-level fingerprints. We also provide the absolute fingerprints.
The methods used to obtain this dataset, as well as the results, are presented in the manuscript "Trends and Uncertainties of Mass-driven Sea-level Change in the Satellite Altimetry Era", published in Earth System Dynamics (https://doi.org/10.5194/esd-2021-80)
