CESM2-CISM2 Transient Last Interglacial Simulations
Listed in National Center for Atmospheric Research
The Transient Last Interglacial dataset contains output from the TransientLIG simulation from 127,000 to 119,000 years before present (127 - 119 ka).
Description
This simulation is with the CESM2.1 at the FV1_gx1v6 resolution coupled to CISM2 at 4 km resolution for Greenland. The ice sheet model and the orbital parameters over time (eccentricity, obliquity, and precession) are accelerated - advancing 5 years for each CESM2 year.
In CAM6, the surface elevation over Greenland is updated every 10 atmosphere years. Offline coupling of BIOME4 distributions every 500 ice-sheet years allows for incorporation of quasi-dynamic vegetation changes [U.S. Geological Survey data release, doi.org/10.5066/P9RPB5KD]. All other forcings (GHGs, aerosols, land-ocean configuration) are kept constant during the TransientLIG simulation.

The dataset also includes a sensitivity simulation (NoBiome) from 127 - 121 ka illustrating the effects of vegetation. This simulation retains the preindustrial no-Anthro vegetation distribution adopted in the CMIP6-PMIP4 127 ka and 6ka equilibrium simulations with CESM2.1 at the FV1_gx1v6 resolution. The TransientLIG and NoBiome simulations are initialized from the CMIP6-PMIP4 lig127ka simulation with CESM2 [doi.org/10.22033/ESGF/CMIP6.7673].
The simulations adopted the initial state of the GrIS from the CESM2-CISM2 JG/BG spinup under pre-industrial climate forcing [doi.org/10.26024/4gt3-9r10].
