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共置的猪皮松替代品，以解决全新世气候的三个非常不同和关键的基本方面，包括降水变异性、温度变异性和火山作用。这三个变量的长期替代记录可以用来驱动和评估大气环流模型，从而为进一步了解全新世气候动力学提供了一个试验场。这个项目的目标是显著改善对北美西部全新世古气候变化的评估。潜在的更广泛的影响包括开发全新世气候测量和分析的数据集，学生参与和支持该项目，在亚利桑那州的树轮研究实验室(LTRR)开发新的教育展品，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奇卡诺人和美洲土著人促进协会(SACNAS)招募和与少数族裔学生合作。该奖项反映了NSF的法定使命，通过使用基金会的智力优势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.
