Xu, C., Sano, M. and Nakatsuka, T.: A 400-year record of hydroclimate variability and local ENSO history in northern Southeast Asia inferred from tree-ring δ18O, Palaeogeography, Palaeoclimatology, Palaeoecology, 386, 588–598, doi:10.1016/j.palaeo.2013.06.025, 2013.

Positive correlation between cellulose d18O and precipitation d18O; the later is positively influenced by air temperature.

Composite tree-ring d18O record representing the average of up to 8 Rocky Mountain Bristlecone Pine (Pinus aristata) trees in any given year of the composite record.

Column 'TR12BECO-chron-NA1', with variable name 'yearEnsemble', was added to the dataset
