Multi-Sensor QPE within MRMS

The Multi-Radar Multi-Sensor (MRMS) system is a suite of hydrometeorological tools developed at the National Severe Storms Laboratory and run operationally by the U.S. National Weather Service. MRMS ingests information from a wide variety of sensors, including weather radars in the U.S. and Canada, rain gauges, and output from numerical weather prediction models. MRMS outputs are produced on a shared 1-km x 1-km Cartesian grid every 2 minutes, over the contiguous U.S. and southern Canada, Alaska, Hawaii, and the Caribbean. In this short course, MRMS developers will explain the overall system and provide in-depth detail on the quantitative precipitation estimates produced within MRMS. The short course will include a demonstration of the MRMS real-time product viewers.
