The 10Be record in laminated travertines is a potential proxy for reconstructing past solar activitydown to the annual scale; however, correcting for the potential influence of climatic or environmental variationsremains challenging. Here, we present an annually resolved 10Be record using travertines from Baishuitai,China, covering the period from 1510 to 1701 CE, along with environmental proxies, to evaluate climaticinfluences and implement corrections to accurately reconstruct solar activity. We demonstrate that the 10Bedeposition in travertines exhibits two environmental impacts: the transport efficiency of atmospheric 10Be intotravertine and the additional 10Be inflow from overland flow associated with rainfall. We show that theseimpacts can be corrected based on iron and potassium contents. The resulting corrected record agrees with ice‐core and tree‐ring records, demonstrating the feasibility of using such carbonate sediment 10Be records toreconstruct past solar activity.
