Reconstruction of summer temperature (June-August) at Mt. Helan, China, from tree-ring stable carbon isotope values since AD 1890

From stable carbon isotope analysis of tree-rings of Chinese pine (Pinus tabulaeformis) from Mt. Helan, China, we found that high-δ13C values were related to high mean temperatures from June to August (T68), and low-δ 13C values corresponded to low T68. From these data, a transfer function has been...

Description
Summary:From stable carbon isotope analysis of tree-rings of Chinese pine (Pinus tabulaeformis) from Mt. Helan, China, we found that high-δ13C values were related to high mean temperatures from June to August (T68), and low-δ 13C values corresponded to low T68. From these data, a transfer function has been used to reconstruct summer temperatures (T68) for the Mt. Helan region. The explained variance of reconstruction is 34.9% (F=15.01, p
