近年来，计算机技术的快速发展使得在一个集中的位置实时传输和集成大容量、多数据库数据成为可能。最近在国家环境预测中心实施的多雷达多传感器（MRMS）系统通过将美国和加拿大接壤的大约180个业务天气雷达整合成具有非常高的空间（1公里）和时间（2分钟）分辨率的无缝国家三维雷达镶嵌图，展示了这种能力。雷达数据可以与高分辨率数值天气预报模型数据、卫星数据以及闪电和雨量计观测数据相结合，生成一套恶劣天气和定量降水估计（QPE）产品。本文概述了MRMS QPE产品的初始运行能力。
Rapid advancements of computer technologies in recent years made the real-time transferring and integration of high-volume, multisource data at a centralized location a possibility. The Multi-Radar Multi-Sensor (MRMS) system recently implemented at the National Centers for Environmental Prediction demonstrates such capabilities by integrating about 180 operational weather radars from the conterminous United States and Canada into a seamless national 3D radar mosaic with very high spatial (1 km) and temporal (2 min) resolution. The radar data can be integrated with high-resolution numerical weather prediction model data, satellite data, and lightning and rain gauge observations to generate a suite of severe weather and quantitative precipitation estimation (QPE) products. This paper provides an overview of the initial operating capabilities of MRMS QPE products.
