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.

该协作项目旨在生产古气候重新分析 - 过去25，000年的气候统计坚固的栅格重建 - 使用在气象界广泛使用的数据同化技术，以结合气候模型和代理的信息，以重建气候气候领域。 重新分析将用于检验有关热带沃克循环和主要季风系统对不断变化的气候背景状态以及地球气候系统中低频（百年至千年级）变化的起源的主要季风系统的反应的假设。具体的目标是检验有关热带气候系统在寒冷和温暖的气候下的行为的假设，并记录和确定百年纪念到千禧年尺度气候变化的动态起源。更广泛的科学社区将获得古气候重新分析，并可以为跨多个学科的研究提供一个社区基准。该项目将支持研究生和博士后候选人，并涉及大量的本科参与数据收集和分析的形式。 该项目还支持与女子力量计划的新合作伙伴关系，以在图森公立学校为中学女孩开发科学教育和外展机会。
