Long term, transient climate data at 1km resolution since the LGM.
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. Paleo orography at high spatial resolution and at each timestep is created by combining high resolution information on glacial cover from current and Last Glacial Maximum (LGM) glacier databases with the interpolation of a dynamic ice sheet model (ICE6G) and a coupling to mean annual temperatures from CCSM3-TraCE21k. Based on the reconstructed paleo orography, mean annual temperature and precipitation was downscaled using the CHELSA V1.2 algorithm.
