Pollen‐recorded bioclimatic variations of the last ~2000 years retrieved from Bayan Nuur in the western Mongolian Plateau
The palaeoclimatic variations during the past ~2000 years in western Mongolia were reconstructed using a high‐resolution pollen sequence obtained from Bayan Nuur. The pollen‐based mean annual precipitation ( MAP ) from Bayan Nuur and the tree ring‐based temperature anomalies from the nearby Altai Mo...
