Transient climate simulation of the last 21,000 years with ECBilt-CLIO

21,000 year long Paleosimulation from 21,000 before present into the pre-industrial era with the model ECBilt-CLIO.

ECBilt-CLIO was forced with the time-dependent ice-sheet topography of Peltier (Science, 265, 195-201, 1994), orbital forcing (Berger, J., Atmos. Sci, 35, 1978), and greenhouse gas forcing (Indermuehle et al., Nature, 398, 1999; Smith e t al., Nature, 400, 1999; Brook et al., Science, 273, 1996; Sowers et al., Science, 301, 2003). The simulation started from a 2000 year long LGM equilibrium simulation. The climate sensitivity in response to carbon dioxide was increased by a factor of two. Further information can be found in Timm and Timmermann (2007).

Annual and seasonal mean data for the atmospheric output have been saved for each model year. Annual mean oceanic output is available with a time resolution of 10 years. First year corresponds to year 21,000 BP. The last year is to be interpreted as year 1 BP but with pre-industrial greenhouse gases.
