Here we present Late Miocene (~11-7 Ma) model boundary conditions used by Knorr et al.  in two files (Paleogeography.nc and Surface_conditions.nc). These boundary conditions relate to Figure 1 in the corresponding study.
The file Paleogeography.nc (0.5°x 0.5° resolution) contains the orography (positive values and zero) and bathymetry (negative values). The file Surface_conditions.nc contains land surface conditions. Besides the glacier mask these surface conditions (3.75°x 3.75° resolution) contain the vegetation distribution that is represented by specifying different land surface parameters including, surface albedo, surface roughness length, field capacity of soil, forest ratio, leaf area index, fractional vegetation cover, and soil data flags (Food and Agriculture Organization soil map) [cf. Hagemann et al., 1999]. For further details regarding the paleogeography reconstruction and proxy-based reconstruction of the Late Miocene vegetation we would like to refer to Micheels et al. , Micheels et al.  and the references therein.
