Collaborative Research: P2C2--Past Precipitation, Temperature, and Volcanism: Multi-Millennial Records from Three Co-located Bristlecone Pine Proxies

该项目旨在开发三种位于同一位置的狐尾松代用物，以解决全新世气候的三个截然不同的关键基本方面，包括降水变率、温度变率和火山作用。这三个变量的长期代理记录可用于驱动和评估一般环流模式，从而为进一步了解全新世气候动力学提供了一个试验场。该项目的目标是显著提高对北美西部全新世尺度古气候变化的评价。潜在的更广泛的影响包括开发全新世气候的新测量和分析数据集，学生参与和支持该项目，在亚利桑那州树木年轮研究实验室（LTRR）开发新的教育展览，每年有超过10,000人（包括K-12，大学生和公众），并通过西华盛顿大学的奇卡诺人和印第安人促进协会（SACNAS）招募少数民族学生并与之合作。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

This project aims to develop three co-located bristlecone pine proxies to address three very different and key fundamental aspects of Holocene climate that include precipitation variability, temperature variability, and volcanism. Long proxy records of these three variables can be used to both drive and evaluate general circulation models thereby providing a testing ground for further understanding of Holocene climate dynamics. The goal of this project is to significantly improve the evaluation of Holocene-scale paleoclimatic change in western North America.The potential Broader Impacts include developing a dataset of new measurements and analyses of Holocene climate, participation and support of students in the project, development of new educational exhibits at the Arizona's Laboratory of Tree-Ring Research (LTRR) which sees over 10,000 individuals per year (including K-12, University students, and the public), and recruiting and working with minority students through the Society for Advancement of Chicanos and Native Americans (SACNAS) via Western Washington University.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
