The Multi-Radar Multi-Sensor (MRMS) project is a fully automated system that rapidly and intelligently integrates data from multiple radars and radar networks, surface and satellite observations, numerical weather prediction (NWP) models, and other data sources to generate seamless, high spatio-temporal resolution mosaics. It is an operational platform utilized by the National Weather Service as well as other government and commercial agencies. It is also a research platform designed to developing cutting-edge algorithms and techniques to improve precipitation estimation used by CIWRO and NSSL.
