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.

该项目旨在开发三个共同定位的狐尾松代理，以解决全新世气候的三个非常不同的和关键的基本方面，包括降水变化，温度变化和火山活动。 这三个变量的长期代理记录可以用来驱动和评估大气环流模式，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改善对北美西部全新世尺度古气候变化的评估。潜在的更广泛影响包括开发一个新的全新世气候测量和分析数据集，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，000人（包括K-12，大学生和公众），通过墨西哥裔和美洲原住民促进协会（SACNAS）招募少数民族学生并与他们合作该奖项反映了NSF的法定使命，并被认为值得通过使用基金会的智力价值和更广泛的评估来支持。影响审查标准。
