Aeolian dust deposits from continent and ocean have been extensively investigated to reflect past changes in source aridity and atmospheric circulations. Aeolian flux (AF) as a quantitative dust proxy has been widely used in both paleoenvironmental reconstruction and numerical simulation. However, available AF data on Chinese Loess Plateau (CLP) is too limited to assess the tempo-spatial variations at glacial-interglacial time scales, and thus cannot be used as robust input parameters in paleoclimate models. Here we investigate eight loess profiles along two north-south transects on the CLP to quantitatively estimated the AF variations over the last glacial-interglacial cycle. We first establish a refined chronological framework based on optically stimulated luminescence chronology and pedostratigraphic correlation. AF was then estimated by multiplying the sedimentation rate and bulk density. The results show that the AF increases from 2-18 g·cm-2·ka-1 in the southeastern CLP to 14-105 g·cm-2·ka-1 in the northwestern CLP. At glacial-interglacial scales, the AF varies from 2-20 g·cm-2·ka-1 during the last interglacial to 8-105 g·cm-2·ka-1 in the last glaciation. Due to more spatial coverage and better age constraints, our AF data can be used to refine the DIRTMAP dataset and to improve the proxy-model comparison.
