Other products, such as probabilities of exceeding a threshold, are separate variables.\n\nThis 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.\n\nNote: `dynamical-catalog>=1.0.1` and `gribberish>=1.8.4` (or `zarr>=3.2 icechunk>=2.0 gribberish>=1.8.4`) are required.", "description_details": "### Source\n\nThe source grib files this archive is constructed from are provided by [NOAA Open Data Dissemination (NODD)](https://www.noaa.gov/information-technology/open-data-dissemination) and accessed from the [AWS Open Data Registry](https://registry.opendata.aws/noaa-rrfs-ops/).\n\n### Storage\n\nStorage for this dataset is generously provided by [AWS Open Data](https://aws.amazon.com/opendata/).\n\n### Chunks\n\nThis dataset is stored in [Zarr](https://zarr.dev/) format, which splits each variable into a grid of **chunks** \u2014 the smallest unit read from storage.
