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置换的毛酮松树代理，以解决全新世气候的三个截然不同和关键的基本方面，其中包括降水性变异性，温度可变性和火山症。 这三个变量的长期代理记录可用于驱动和评估一般循环模型，从而提供了一个测试场，以进一步了解全新世气候动力学。 该项目的目的是显着改善北美西部的全新世级古气候变化的评估。潜在的广泛影响包括开发新的测量数据和全新世气候的分析，该项目中的学生的参与和支持，在亚利桑那州的公共研究（LTRR）（ltrr）的实验室（包括10,000年）（包括10,000年）（包括10,000年），众所周知，在亚利桑那州的实验室中开发了新的教育性展览，并包括10,000 ke，以及涉及10,000 ke and of 10,000（包括KAR），并包括10,000 ke and of 10,000（包括KAR）。通过西华盛顿大学通过芝士和美洲原住民（SACNA）的促进协会与少数族裔学生合作。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子优点和更广泛的影响来通过评估来支持的。
