title: Relative sea level changes in the southern Baltic Sea from glacial isostatic adjustment modelling based on a spherically symmetric, compressible, Maxwell-viscoelastic earth model and two different global ice models

description: We provide relative sea-level (RSL) changes for the last 25,000 years for the southern Baltic Sea based on glacial isostatic adjustment (GIA) modelling using either the global ANU-ICE model with the European ice model part from Lambeck (1993) and Lambeck et al. (1998), and 9 different earth models, or the global ice model ICE-5G (Peltier, 2004) and 9 different earth models. The results are provided in 1x1 grids for an area from 5-25 degrees E longitude and 52-60 degrees N latitude. The software ICEAGE (Kaufmann, 2004) is used for calculating the grids. For details on the modelling and model input, we refer the reader to Steffen et al. (2014). 

The attached files represent RSL calculations from the best-fitting models to RSL data of certain regions in the southern Baltic Sea, which are specified in Table 1 of Steffen et al. (2014). The files are named rsl_Steffen-etal14_balticsea_{earth-model}_{ice-model}.nc where the {earth-model}_{ice-model} code refers to the three-layer earth model-ice model combination.
