09300033KrajewskiThis award will support custom software development to support a network of mobile, scanning, low power, X-band polarimetric Doppler radars acquired recently through NSF funding. The Doppler network's effective use requires internet-based remote control, real-time data visualization and data quality control software and tools for generating precipitation cell observation products. In addition, data management and archiving are needed. The software, archive and control systems will enhance observational capabilities of the fully developed mobile Doppler network and will allow scientists to address long-standing questions of how to predict flooding in ungauged basins. The mobile Doppler network was based on the enhanced capabilities for high spatial and temporal resolution imaging (manufacturer specifies 1.5 deg beamwidth with 250 square meter pixels at 10 km range with 1-2 minute scan times). Precipitation distribution and characterization of 3-D wind velocity fields will be characterized by the X-band polarimetric radars network which can achieve results far superior to existing static national NOAA/NWS network of NEXRAD radars (which are limited to 4 square km pixel resolution). The small (6 m diameter antenna) X-band radars will be trailer-mounted for mobile field deployment. As emphasized in review of the funded MRI proposal, the mobile radar network will enable PIs to addresses a first order driving mechanism of surface and ground water dynamics. The software proposed here will allow unique data acquisition and dissemination. The PI will coordinate all activities with assistance from the Co-PI. The radar units are currently being delivered. During year one, the software design and database structure will be developed along with radar control routines. In year two, algorithms will be refined while real-time data will be collected. New and improved components will be identified and developed. Two PhD students will be involved in the software development. The system will serve as a prototype for high-resolution observations and assist in flood research (especially in fast-responding basins). The heretofore unavailable spatial and temporal data will feed into improved hydrologic cycle models. Data will feed into the Prediction in Ungauged Basins initiative, and the NSF-supported WATERS Network. The software will have a web interface, thus public and educational usage will be facilitated. Two PhD students will be directly involved, and the radar system software will be incorporated into two class modules.***

该合同将支持定制软件开发，以支持最近通过NSF基金获得的移动、扫描、低功耗、x波段偏振多普勒雷达网络。多普勒网络的有效使用需要基于互联网的远程控制、实时数据可视化和数据质量控制软件以及生成降水细胞观测产品的工具。此外，还需要数据管理和存档。软件、档案和控制系统将增强完全开发的移动多普勒网络的观测能力，并将使科学家能够解决如何在未测量的盆地预测洪水的长期问题。移动多普勒网络基于增强的高空间和时间分辨率成像能力（制造商指定1.5度波束宽度，250平方米像素，10公里范围，1-2分钟扫描时间）。降水分布和三维风速场的特征将由x波段极化雷达网络表征，其结果远远优于现有的静态国家NOAA/NWS NEXRAD雷达网络（仅限于4平方公里像素分辨率）。小型（6米直径天线）x波段雷达将安装在拖车上，用于移动战场部署。正如在审查资助的MRI提案中所强调的那样，移动雷达网络将使pi能够解决地表和地下水动力学的一级驱动机制。这里提出的软件将允许独特的数据采集和传播。PI将在联合PI的协助下协调所有活动。雷达装置目前正在交付中。在第一年，软件设计和数据库结构将与雷达控制例程一起开发。在第二年，将改进算法，同时收集实时数据。将确定和开发新的和改进的组件。两名博士生将参与软件开发。该系统将作为高分辨率观测的原型，并协助洪水研究（特别是在快速反应的流域）。迄今无法获得的时空数据将用于改进的水文循环模型。数据将提供给未测量盆地预测计划和nsf支持的WATERS网络。该软件将有一个网络界面，因此将促进公众和教育使用。两名博士生将直接参与，雷达系统软件将被纳入两个班级模块
