Abstract

This is a synthetic dataset. It was created from the outputs of the glacial isostatic adjustment model VILMA (Klemann et al. 2008). It consists of realtive sea level (RSL) data on a global regular grid. The resolution is 256 x 512 points (Lat x Lon). The tomporal range is from 123 ka BP until present day. Time steps vary between 2.5 kyrs at the beginning and 0.5 kyrs towards the end. The data were created for a specific configuration of the GIA model: lithosphere thickness = 60 km, lithosphere viscosity = 1.0E31 Pa s, upper mantle thickness = 610 km, upper mantle viscosity = 1.0E20 Pa s, lower mantle thickness = 3,221 km, lower mantle viscosity = 1.0E21 Pa s. The RSL data are accompanied by a observation locations mask. This mask was used to identify those locations in the global RSL dataset where real observations are available.

The RSL data are accompanied by observation locations masks. These masks were used to mark those locations in the global RSL dataset where real-life observations are available in order to restrict usage of the synthetic data to those locations.
