Sediment cores JB-A (9.76 m) and JPS-1 (0.32 m) were collected in August 2012 using the piston corer and gravity core sampler, respectively. The ages of JB-A and JPS-1 cores are 6092 years and 100 years based on the14C dates and the combined ages of excess 210Pb and 137Cs. Geochemical proxies of EASM precipitation were reconstructed by elemental compositions such as SiO2, TiO2, Al2O3, Fe2O3, MnO, CaO, Na2O, K2O, P2O5, CIA, and LOI, analyzed with the glass-bead XRF quantitative method. Multi-proxies of EAWM wind strength were reconstructed from the Mn/Fe ratio, grain-sizes, and biogenic silica, analyzed with the glass-bead XRF quantitative method, the laser diffraction, and the ICP-AES, respectively.The study was further supported by the Japan Geographic Data Center https://www.kokudo.or.jp/grant/.129.03173943.986897Lake JingpoJapan Society for the Promotion of Sciencehttps://doi.org/10.13039/50110000169116H05643Relationship between water resource and environmental change investigated by saline lake level changesJapan Society for the Promotion of Sciencehttps://doi.org/10.13039/50110000169117H05128Climatic impact on terrestrial environments and human migration in central Asia investigated by high-resolution analyses of lacustrine sediment coreJapan Society for the Promotion of Sciencehttps://doi.org/10.13039/50110000169122H00560Holocene terrestrial response to climate changes by high resolution analyses of freshwater lake sediments
