Funding is provided to develop replicated, multi-century tree-ring width and intra-to-inter annual oxygen isotopic proxy records of precipitation in North Queensland, Australia from plantation tree samples and long lived wild specimens of Callitris intratropica and Araucaria cunninghamii. The overarching scientific goal of the project is to develop a reliable archive of climate data from tropical tress for which classic annual growth bands are not formed. The region of study is strongly affected by El Nino-Southern Oscillation (ENSO) activity, as well as longer term droughts with great impact on agriculture and water resources.The broader impacts involve strong international collaboration, supporting a graduate student and post-doctoral scholar, and bringing a different quantitative perspective to the analysis of paleoclimate data.

提供资金用于开发复制的、多世纪树木年轮宽度和年际间降水的氧同位素代用记录，这些代用记录来自澳大利亚北昆士兰的人工树样本和长寿的calitris intratropica和Araucaria cunninghamii野生标本。该项目的首要科学目标是建立一个可靠的热带树木气候数据档案，因为热带树木没有形成典型的年生长带。研究区受厄尔尼诺-南方涛动（ENSO）活动的强烈影响，以及对农业和水资源影响较大的长期干旱。更广泛的影响包括强有力的国际合作，支持研究生和博士后学者，并为古气候数据分析带来不同的定量视角。
