The International Tree-Ring Data Bank (ITRDB) contains hundreds of tree-ring data sets that are useful for the study of climate variability and change, including attribution studies of possible climate forcing by greenhouse gases. The mean annual tree-ring chronologies, however, which are typically used in dendroclimatic studies, do not include associated meta-data that explain how the chronologies were developed from the raw data. This award supports re-standardizing the most important subset of tree-ring data sets for climate studies in the ITRDB, i.e. those that begin on or before 1700. The important features of the tree-ring chronologies will be documented as they relate to the conservation of low-frequency climate variability. These re-standardized tree-ring chronologies will be placed in the ITRDB as a separate, enhanced, full-documented library that will be freely available to the scientific community.

国际树轮数据库（树轮数据库）包含数百个树轮数据集，可用于研究气候变异性和变化，包括对温室气体可能造成的气候强迫的归因研究。 然而，通常用于树木年轮气候研究的平均年树木年轮年表并不包括相关的元数据，这些元数据解释了年表是如何从原始数据发展而来的。 该奖项支持重新标准化ITRDB气候研究中最重要的树木年轮数据集子集，即那些开始于1700年或之前的数据集。 将记录树木年轮年表的重要特征，因为这些特征与保护低频气候变异性有关。 这些重新标准化的树木年轮年表将作为一个单独的、增强的、完整的文档库被放置在ITRDB中，科学界可以免费使用。
