Collaborative Research: Reconstruction of Drought and Streamflow over the Coterminous US from Tree Rings with Extensions into Mexico and Canada

该奖项是为了支持一项合作研究（亚利桑那大学、科罗拉多大学和哥伦比亚大学，后者由美国海洋和大气管理局的一项单独的奖助金资助），通过（a）改进和在地理上扩大根据树木年轮重建北美干旱的现有网格，（B）考虑新的干旱测量方法，（c）专门开发技术，用于重建和分析与通过水库调度和水资源分配进行干旱管理有关的测量流量系列的关键属性，（d）研究新的统计方法，以改进重建和时空干旱变异性分析。

This award is for support of a collaborative study (University of Arizona, University of Colorado, and Columbia University, the latter funded under a separate award from NOAA) to considerably broaden the scope of past drought reconstructions from tree rings, now based on the Palmer Drought Severity Index, by (a) improving and geographically expanding the existing grid of North American drought reconstructions from tree rings, (b) considering new measures of drought, (c) specifically developing techniques for reconstructing and analyzing key attributes of gaged streamflow series that are relevant for drought management through reservoir operation and water resource allocation, and (d) investigating new statistical methods for improving the reconstructions and the analysis of space-time drought variability.
