| Zusammenfassung |
| We describe a set of early Eocene (~ 55 Ma) climate model boundary
conditions constructed in a self-consistent reference frame and incorporating
recent data and methodologies. Given the growing need for uniform
experimental design within the Eocene climate modelling community and the
challenges faced in simulating the prominent features of Eocene climate, we
make publicly available our data sets of Eocene topography, bathymetry,
tidal dissipation, vegetation, aerosol distributions and river runoff. Major
improvements in our boundary conditions over previous efforts include the
implementation of the ANTscape palaeotopography of Antarctica, more accurate
representations of the Drake Passage and Tasman Gateway, as well as an
approximation of sub grid cell topographic variability. Our boundary
conditions also include for the first time modelled estimates of Eocene
aerosol distributions and tidal dissipation, both consistent with our
palaeotopography and palaeobathymetry. The resolution of our data sets is
unprecedented and will facilitate high resolution climate simulations. In
light of the inherent uncertainties involved in reconstructing global
boundary conditions for past time periods these data sets should be considered as
one interpretation of the available data and users are encouraged to modify
them according to their needs and interpretations. This paper marks the
beginning of a process for reconstructing a set of accurate, open-access
Eocene boundary conditions for use in climate models. |
