Weathering data of LV55-38-3 in the Sea of Okhotsk and simulated rainfall data acorss different latitudes

This dataset includes chemical weathering proxies(CIA,CIX, K/Al ratio, and smectite/illite) and provenance proxy (La/Yb, Nd/Gd, and Sr-Nd isotopic))of Site LV55-38-3 and some surface sediments. They are all analyzed based on the clay-sized fractions. It also includes the data of simulated rainfall changes in the Northeast Russia(NER), Northeast China (NEC), South Asia (SA) as well as in Central West Africa (CWA) during past 240 ka.
