The goal of this project is to synthesize existing tree-ring proxy data (ring width, stable oxygen isotope ratios, blue light intensity, and gridded Palmer Drought Severity Index (PDSI) estimates) to create a seasonal-resolution paleo-streamflow reconstruction for Southeast Asia. The investigators will compare the reconstruction to paleo-streamflow estimates generated by forcing a Southeast Asia hydrological model with Paleoclimate Modelling Intercomparison Project Phase 4 (PMIP4) hydroclimate variables for the last millennium. The comparisons will include assessment of variability in modeled streamflow and comparison of dominant modes and spatial/temporal coherency of variability in the proxies and models. These analyses seek to illuminate the mechanisms that drive the observed dynamics. The project includes support of two early career researchers from underrepresented groups, a graduate student and plans to include undergraduates in the research, development of an interactive public-facing web application with educational materials, and visualization of streamflow through space and time as part of an effort to help create more effective water management strategies for a densely populated region.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.

该项目的目的是综合现有的树环代理数据（环宽，稳定的氧同位素比，蓝色光强度和网格的帕尔默干旱严重程度指数（PDSI）估计），以创建季节性分辨率的Southeast Asia的古流式流程流程。研究人员将通过迫使向东南亚水文模型与古气候建模相比项目4（PMIP4）氢化气候变量进行比较，将重建与古流流估计值进行比较。比较将包括评估模型流流中的可变性以及对代理和模型中变异性的主导模式的比较以及空间/时间相干性。这些分析试图阐明驱动观察到的动力学的机制。该项目包括来自代表性不足的小组的两名早期职业研究人员的支持，他们的一名研究生，并计划在研究中包括本科生，开发具有教育材料的互动式​​公共面向公共的网络应用程序以及通过空间和时间对流量的可视化流量，作为一项努力的一部分，以帮助建立更有效的水管理策略，以反映nsf的基础奖，并以此为基础，以反映出NSF的宣传奖，并以此为基础。优点和更广泛的影响审查标准。
