| + | * //MH: a full set of early Eocene boundary conditions submitted to Geoscientific Model Development which will be freely available (Nick Herold is spearheading this). It will include topo,bathymetry,veg, tidal dissipation, and aerosol forcing files at 1°x1° among other parameters. the DEM is based on a merging of Markwick's topo and Mueller's bathy/rotations.... it should include everything necessary setting up a coupled GCM run (nothing is turnkey of course, but all the fundamentals are there). hopefully it might provide a basis for future intercomparison efforts and provide a baseline for subsequent modification or comparison. the necessary scripts for rotation the topo/veg to earlier and later time intevals (say 65 and 35mya) will also be provided... Once the article is submitted, we will make it available for perusal and criticism...// | ||

| * //GF: I think a radical way to do this would be to move away from simple difference to modern type studies that have been done to date, instead we could try to look across a number of natural warming events and see whether the models capture the warming the geological record shows. So for instance, pre, peak and post PETM, MECO and EECO - do the models show similar trajectories to the data? CO2 would be much better constrained this way and so will the SSTs (e.g. most of the TEX86 uncertainty in your Eocene paper is due to calibration, for these shorter time periods you could use delta T change which is largely independent of calibration).// | * //GF: I think a radical way to do this would be to move away from simple difference to modern type studies that have been done to date, instead we could try to look across a number of natural warming events and see whether the models capture the warming the geological record shows.
