1000 year-long summer precipitation record for the North-western Alps (Lake Oeschinen)@en

Here, we present an annually-resolved record of warm season (MJJA) precipitation from the varved (annually laminated) sediments of proglacial Lake Oeschinen (46 30 N-7 44 E, 1580 m, NW Swiss Alps) back to AD 884. This data set is inferred from the thickness of annual sediment deposits in the sediments. The chronology of the sediment record is based on multiple varve counts and validated with historical floods chronicled in written documents (back to the 14th century), 201Pb, 137Cs, and 14C AMS dates.
