Objective:The main goal of the proposal is the development of a network of three short-range dual polarized X-band Doppler radars for the Puerto Rico's west coast. This weather-sensing network will achieve breakthrough improvements in sensitivity and resolution for sampling storms, thermodynamic state, and other critical variables throughout the entire troposphere.Intellectual Merit:In Puerto Rico, where complex orography limits the use of traditional long-range radar systems, the deployment of a network of short range radars is an attractive alternative to observe the weather.While current technology has been successfully used for many years to provide weather forecast, better coverage and resolution of the lower atmosphere is desired to help the scientists to understand weather phenomena that is undetected under the long-range radar beam. To achieve this goal, a network consisting of three X-band radars that will have the ability to monitor the earth's lower troposphere is proposed. The network will provide precise weather forecast to a region in Puerto Rico plagued by intense rain and flash floods, but the lack of precise data and the complex orography of the Island has lead to poor prediction of these events.Broader Impact:The proposed instrument will help fill the coverage gaps in the lower troposphere currently undetected by NEXRAD in Western P.R. As a result this will help in the protection of life/property in the West of the Island in the event of severe weather conditions. This technology can then be used in regions in the World with similar geographical and weather conditions as in Puerto Rico.

目的：该提案的主要目标是为波多黎各西海岸建立一个由三个短程双极化X波段多普勒雷达组成的网络。这一天气传感网络将在采样风暴、热力学状态和整个对流层的其他关键变量的灵敏度和分辨率方面实现突破性的改进。在波多黎各，复杂的地形限制了传统远程雷达系统的使用，部署短程雷达网络是观测天气的一个有吸引力的选择。虽然目前的技术已成功地用于提供天气预报多年，更好的低层大气的覆盖范围和分辨率是必要的，以帮助科学家了解在远程雷达波束下无法探测到的天气现象。为了实现这一目标，提出了一个由三个X波段雷达组成的网络，该雷达将有能力监测地球的低对流层。该网络将为波多黎各地区提供精确的天气预报，该地区受到暴雨和山洪暴发的困扰，但由于缺乏精确的数据和该岛复杂的地形，导致这些事件的预测不佳。更广泛的影响：拟议的仪器将有助于填补目前在波多黎各西部NEXRAD未检测到的对流层低层覆盖空白。因此，这将有助于在恶劣天气条件下保护该岛西部的生命/财产。 这项技术可以在世界上地理和天气条件与波多黎各相似的地区使用。
