NOAA MRMS

The NOAA Multi-Radar/Multi-Sensor System (MRMS) integrates data from multiple radars and radar networks, surface observations, numerical weather prediction (NWP) models, and climatology to generate seamless, high spatio-temporal resolution mosaics at low latency focused on hail, wind, tornado, quantitative precipitation estimations, convection, icing, and turbulence.

dynamical.org republishes NOAA MRMS as free, analysis-ready Icechunk Zarr archives — open them directly with Xarray, no GRIB wrangling or bulk downloads.
