These are the relative sea surface height (SSH) data, which was used in the construction of figures for the Fifth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC-AR5). The data include 10 geophysical sources that drive long-term changes in relative SSH:
- 5 ice components (Greenland dynamic ice and surface mass balance, Antarctic dynamic ice and surface mass balance, and glaciers),
- 3 ocean-related components, all of which are derived from CMIP5 models (dynamic SSH, global thermosteric SSH anomaly, and the inverse barometer effect from the atmosphere),
- land water storage (also called terrestrial water),
- and glacial isostatic adjustment (as a change in sea level relative to land).
In addition to the relatively few fields actually used in the IPCC-AR5 figures, all individual components are available here, both as maps of 20-yr mean differences (always the 2081-2100 mean minus the 1986-2005 mean), and as time series with the 1986-2005 mean set as the common zero SSH anomaly value.
All processing methods and data sources are defined in chapter 13 of the Supplementary Material (see References). Some further details, including combining uncertainties from different components, are included in a readme file.
