NOAA HRRR - dynamical.org Icechunk Zarr

The High-Resolution Rapid Refresh (HRRR) is a NOAA real-time 3-km resolution, hourly updated, cloud-resolving, convection-allowing atmospheric model, initialized by 3km grids with 3km radar assimilation. Radar data is assimilated in the HRRR every 15 min over a 1-h period adding further detail to that provided by the hourly data assimilation from the 13km radar-enhanced Rapid Refresh. These datasets have been translated to cloud-optimized Icechunk Zarr format by [dynamical.org](https://dynamical
