Data are measured for the southern hemisphere November-April growing season. Also included are datafile BEB14.dat and a matlab script to plot the data as in Fig 2(a) of Boysen et al. 2014. In the datafile BEB14.dat, data are identifed by the year growth began, i.e. 1995 data correspond to the growing season Nov 1995 - Apr 1996. To develop a composite, annually resolved, calendar-dated oxygen isotope time series, we used the tropical isotope dendroclimatology hypothesis to assign January/February calendar age to isotopic minima within each dendrochronologically dated growth increment, assuming that each minimum in the isotope chronology represents the climatologically average wettest month of the November-April rainy season in northern Queensland. For each data series, we then linearly interpolated each 4–8 point set of intra-seasonal d18O values to produce a uniform four d18O interpolates within each November-April growing season. This permitted us to composite data across the three sample series on a common intraseasonal time scale.

We measured tree-ring width and oxygen isotopic composition (d18O) of alpha-cellulose from Agathis robusta (Queensland Kauri) samples collected in the Atherton Tablelands, Queensland, Australia. Standard ring-width chronologies yielded low internal consistency due to the frequent presence of false ring-like anatomical features. However, in a detailed examination of the most recent 15 years of growth (1995-2010), we found significant correlation between d18O and local precipitation, the latter associated with ENSO activity. The results are consistent with process-based forward modeling of the oxygen isotopic composition of alpha-cellulose. The d18O record also enabled us to confirm the presence of a false growth ring in one of the three samples in the composite record, and to determine that it occurred as a consequence of anomalously low rainfall in the middle of the 2004/5 rainy season. The combination of incremental growth and isotopic measures may be a powerful approach to development of long-term (150+ year) ENSO reconstructions from the terrestrial tropics of Australasia.
