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.

CHELSA-TraCE21k data provides monthly climate data for temperature and precipitation at 30 arcsec spatial resolution in 100-yeartime steps for the last 21,000 years.

The transient climate evolution of the last 21,000 years (Last Glacial Maximum to present) provides key observations for constraining climate sensitivity and understanding abrupt climate change. A synchronously coupled atmosphere-ocean general circulation model simulation of the last 21,000 years has been completed using the CCSM3.

This TraCE-21ka dataset contains the monthly atmospheric output from the transient simulation with CCSM3 of the climate from the Last Glacial Maximum (LGM) to Present. These results are from a fully-coupled, non-accelerated atmosphere-ocean-sea ice-land surface simulation at the T31_gx3 resolution.
