Description:

  • Rights: Freely Available
  • summary: This TraCE-21ka dataset contains output from the full TraCE simulation from 22,000 years before present (22ka) to 1990 CE as well as single-forcing sensitivity simulations of varying lengths. These results are from a fully-coupled, non-accelerated atmosphere-ocean-sea ice-land surface CCSM3 simulation at the T31_gx3 resolution. For the full TraCE simulation, the model is forced with transient greenhouse gas concentrations and orbitally-driven insolation changes. Transient boundary conditions include the ICE-5G ice sheets - extent and topography, and changing paleogeography as sea level rises from its Last Glacial Maximum low stand to modern levels. We also prescribe a transient scenario of meltwater forcing to the oceans from the retreating ice sheets. Vegetation is prognostic. The following CCSM3 simulations are available: [TraCE] full TraCE simulation, with transient forcing changes in greenhouse gases, orbitally-driven insolation variations, ice sheets and meltwater fluxes. [TraCE-ORB] with only transient orbital forcing, all other forcings and boundary conditions remain at the full TraCE state of 22ka. [TraCE-GHG] with only transient greenhouse gas forcing, all other forcings and boundary conditions remain at the full TraCE state of 22ka. [TraCE-ICE] with only changing continental ice sheets, all other forcings and boundary conditions remain at the full TraCE state of 19ka. [TraCE-MWF] with only transient Northern Hemisphere meltwater fluxes, all other forcings and boundary conditions remain at the full TraCE state of 19ka. [TraCE-ORB-17ka] with only transient orbital forcing, all other forcings and boundary conditions remain at the full TraCE state of 17ka. [TraCE-GHG-17ka] with only transient greenhouse gas forcing, all other forcings and boundary conditions remain at the full TraCE state of 17ka.
