Human Dispersal Simulation over the past 125 ka

Datasets:

• arrival time: Time (ka) since last continuous human settlement for time-varying climate conditions following the transient scenario A simulation (early exit scenario)
• climate forcing: Climate forcing for Human Dispersal Model over the past 125 ka
• human density: 1000 year snapshots of the simulated evolution of human density (individuals per 100 km^2) over the past 125 thousand years using the parameters of scenario A (early exit) experiment

To quantify the effects of climate on human dispersal over the last glacial period, a numerical reaction/diffusion human dispersal model was used. The model is forced by time-varying temperature, net primary production, desert fraction and sea level boundary conditions obtained from a transient glacial/interglacial global earth system model simulation covering the last 125 ka, an estimate of millennial-scale variability and sea level reconstructions, respectively.
