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 climatology to generate seamless, high spatio-temporal resolution mosaics. It is both an operational platform utilized by the National Weather Service and other government agencies and a research platform to developing cutting-edge algorithms and techniques to improve precipitation estimation.


The purpose of this web page is to provide end-users of the MRMS quantitative precipitation estimation (QPE) products information regarding recent code changes and links to training, documentation, and forums related to MRMS QPE.
