A modified method, which is based on standard protocols [Green, 1963; Loader et al., 1997], was used to extract cellulose component from whole wood. 18O/16O ratios using a continuous flow isotope ratio mass spectrometer (Thermo Fisher Scientific Delta V Advantage) coupled to an elemental analyzer (Thermo Fisher Scientific Thermal Conversion/Elemental Analyzer) via a Conflo III interface.

Please check isotopeInterpretation1_name: can this be changed to a standardized term? eg. P_isotope (GF)

TP (31/12/19): climate interpretations (P-negative, T_air-positive) were removed from isotopeInterpretation2 and 3, ; OCh-S: changed; OCh-S:WEBa8749551 needs to be renamed to TR13SAWA00

Instrumental calibration. The I´18O value of precipitation is negatively correlated with the amount of precipitation at low latitudes, which is known as the a€œamount effecta€

plant water is linked to precipitation, and the isotope composition of precipitation is negatively correlated with P amount
