Description: |
    The RRFS Ensemble Forecast System (REFS) is a National Oceanic and Atmospheric Administration (NOAA) National Centers for Environmental Prediction (NCEP) ensemble product system. It produces ensemble products on a 3 km grid, including means, spreads and probabilities of exceeding thresholds, from the current and 6 hour old cycles of the deterministic Rapid Refresh Forecast System (RRFS) and its ensemble (RRFS ENS), plus two HRRR members over the continental United States.

    NOAA REFS is pre-operational, so expect changes to the model data and to the structure of this dataset.

    These datasets have been translated to cloud-optimized Icechunk Zarr format by [dynamical.org](https://dynamical.org).
