This collaborative project aims to produce a Paleoclimate Reanalysis - a statistically robust gridded reconstruction of climate spanning the last 25,000 years - using a data assimilation technique widely used in the meteorological community in order to combine information from climate models and proxies to reconstruct gridded climate fields. The Reanalysis will be used to test hypotheses regarding the response of the tropical Walker circulation and the major monsoon systems to changing climate background states and the origin of low-frequency (centennial to millennial-scale) variability in the Earth's climate system. The specific goal is to test hypotheses regarding the behavior of the tropical climate system under cold and warm climates and to document and identify the dynamical origin of centennial-to millennial-scale climate variability.The Paleoclimate Reanalysis will be available to the wider science community and could provide a community benchmark to benefit research across multiple disciplines. This project will support a graduate student and postdoctoral candidate as well as involve substantial undergraduate participation in the form of data collection and analysis. This project also support a new partnership with the Girl Power program to develop science education and outreach opportunities for middle school girls in a Tucson public school.

该合作项目旨在进行古气候再分析——对过去 25,000 年的气候进行统计上稳健的网格重建——使用气象界广泛使用的数据同化技术，以便结合来自气候模型和代理的信息来重建网格气候场。 再分析将用于检验有关热带沃克环流和主要季风系统对气候背景状态变化的响应以及地球气候系统低频（百年至千年尺度）变化起源的假设。具体目标是测试有关热带气候系统在寒冷和温暖气候下行为的假设，并记录和确定百年至千年尺度气候变化的动力起源。古气候再分析将提供给更广泛的科学界和可以提供一个社区基准，以促进跨学科的研究。该项目将支持研究生和博士后候选人，并让本科生以数据收集和分析的形式大量参与。 该项目还支持与“女孩力量”计划建立新的伙伴关系，为图森公立学校的中学生开发科学教育和外展机会。
