The deployment of the U.S. NEXRAD network has provided meteorologists with critical information towards the issuance of warnings for tornadoes, severe storms, and flash floods. In the early years, radar products were mostly based on single radar with little information from other sources due to limited bandwidth for transmitting large volume data in real time. As a result, the quality and extent of radar applications were limited. Rapid advancements of computer and telecommunication technologies made possible the real-time transferring and integration of high-volume, multi-source data at a centralized location. The multi-radar multi-sensor (MRMS) system recently implemented at the NCEP demonstrates such capabilities by integrating base level data from ~180 operational weather radars from conterminous U.S. and Canada into a seamless national 3-D radar mosaic with very high spatial (1 km) and temporal (2 min) resolution. The radar data is integrated with high-resolution numerical weather prediction model data, satellite data, lightning and rain gauge observations to generate a suite of severe weather and quantitative precipitation estimation (QPE) products. The talk provides an overview of operating capabilities of the MRMS QPE products.
