A 150-year record obtained from Polylepis spp. showed a significant negative relationship between d18O and March precipitation

Source water d18O is determined by P_isotopes, which is strongly influenced by precipitation amount.

A 150-year record obtained from Polylepis spp. also showed a significant negative relationship between d18O and March precipitation

Column 'TR11BAVO-chron-NA1', with variable name 'yearEnsemble', was added to the dataset
