CAREER: A Research and Education Program in Dynamical Paleoclimatology

这个职业奖资助动力古气候学的研究和教育计划-在现代物理气候学的背景下研究古气候观测。支持这项研究的基本思想是，系统的同化古代理观测到一个模型的系统允许简明的测试竞争的假设，古气候变化的根本原因。该战略还提供了独特的机会，以调查气候代用指标形成的基本地球物理控制，并提高基于代用指标的气候重建的精度和准确性。该研究的具体目标包括：1）通过对秘鲁西北沿海热带树木进行重复的高分辨率稳定同位素测量，开发新的代用降雨数据，以通过减少陆地热带覆盖范围的空间和时间差距来提高热带气候场重建的精度和准确性; 2）使用一个过程（即，木材稳定同位素组成的正演模型。提出了正向和反向的相互比较（即，3）古气候模式--利用多代理数据网络和大尺度气候动力学的简单模式进行数据综合; 4）开发、实施和评估古气候技术研究生水平调查课程;和5）开发，实施和评估天气和气候的入门课程，这是敏感的Tohono O 'odham民族的世界观。这门课将在Tohono O 'odham社区学院（TOCC）授课，并将有助于提高TOCC的科学课程，为O' odham学生在亚利桑那大学（及以后）攻读四年制学位和研究机会创造一个指导途径，并有助于增强古气候研究和教育领域的多样性。

This CAREER award funds a research and education program in dynamical paleoclimatology - the study of paleoclimatic observations within the context of modern physical climatology. The basic idea supporting the research is that the systematic assimilation of paleo-proxy observations into a model's system permits concise testing of competing hypotheses regarding the root causes of paleoclimate variations. The strategy also provides unique opportunities to investigate the fundamental biogeophysical controls on climate proxy formation and improve the precision and accuracy of proxy-based reconstructions of climate. The specific goals of the research include: 1) Development of new proxy rainfall data from replicated, high-resolution stable isotope measurements made on tropical trees in northwest coastal Peru to improve the precision and accuracy of tropical climate field reconstructions by alleviating spatial and temporal gaps in coverage in the terrestrial tropics; 2) Interpretation of new paleoclimate data using a process (i.e., forward) model of stable isotopic composition of wood. It is proposed that the inter-comparison of forward and inverse (i.e., statistical) models will improve the quality of climate reconstructions; 3) Paleoclimatic model-data syntheses using multi-proxy data networks and simple models of large-scale climate dynamics; 4) Development, implementation, and assessment of a graduate-level survey course in paleoclimatological techniques; and 5) Development, implementation, and assessment of an introductory course in weather and climate, that is sensitive to the worldview of the Tohono O'odham Nation. This specific class will be taught at the Tohono O'odham Community College (TOCC) and will help enhance the science curriculum at TOCC, create a mentored pathway for O'odham students to pursue four-year degrees and research opportunities at the University of Arizona (and beyond), and help enhance diversity in the field of paleoclimate research and education.
