The Rapid Refresh Forecast System (RRFS) is a National Oceanic and Atmospheric Administration (NOAA) National Centers for Environmental Prediction (NCEP) convection-allowing weather forecast model with a 3 km grid, built on the Unified Forecast System. The RRFS ensemble (RRFS ENS) adds five perturbed members to this deterministic forecast, and REFS combines both with HRRR into ensemble products.
NOAA RRFS is pre-operational, so expect changes to the model data and to the structure of this dataset.
This dataset is an archive of past and present RRFS forecasts, optimized for spatial (map) access patterns. Forecasts are identified by an initialization time (init_time) denoting the start time of the model run, and step forward hourly along the lead_time dimension out to 84 hours.
This dataset uses the native RRFS Lambert Conformal Conic projection, with spatial indexing along the x and y dimensions. The example notebook shows how to use the embedded spatial reference to select geographic areas of interest.
Variables on pressure levels, fixed heights above mean sea level and soil depths live in the pressure_level, height_above_mean_sea_level and depth_below_ground groups.
Note: dynamical-catalog>=1.0.1 and gribberish>=1.8.4 (or zarr>=3.2 icechunk>=2.0 gribberish>=1.8.4) are required.
