Total climate-driven regional sea level projections on a global 0.5x0.5° grid. Projection is a combination of ocean dynamic sea level fields and steric global contribution from the ISIMIP GCMs, and the fingerprints from glaciers and the Greenland and Antarctic ice sheets. The time-dependent fingerpints were generated by scaling a time-independent fingerprint (see Bamber and Riva 2010) with the respective global timeseries for each contribution. Uncertainty for fingerprints is only from the global timeseries. Data is available for following time periods: historical (1861-2005), rcp26 (2006-2099; HadGEM2-ES and IPSL-CM5A-LR extended to 2299), rcp60 (2006-2099) (See below for detailed information).

Caveats
Ocean data is in some cases provided on shorter time spans than the respective global mean temperature data, which drives the glacier and ice sheet contributions. In this dataset, we use the global mean temperature time axis, so that the single contributions are fully present. This leads in some cases to missing values at the beginning and/or the end of the ocean and total timeseries. In some cases (specify when cluster is back), missing values extend to 2100-2300. This dataset does not include a contribution from land water storage. All values are relative to spatial mean value in the year 1861. Thus, the fingerprints, as scaled from global, are flat (i.e. zero at every grid point) 1861. The spatial structure of total slr in 1861 reflects the ocean dynamic pattern.
Only the variable 'total' is intended for use for impact modelling. The other variables are provided for interest only.
