This dataset is comprised of the output from kerchunk's scan_grib across the entire AWS-hosted HRRR forecast files, including pressure levels, surface, and sub-hourly, but not native levels.
Each grib message is its own json file, and each init time is its own zip containing the whole extracted json files for all the forecast times for that init time. Once the kerchunk extraction is 
complete, the plan is to combine them so that they can be opened in a single call to Xarray as one very large dataset. Alternatively, they might be split into different ones, or versions of HRRR, but 
we'll see. Additionally, the plan is to also add versions that can pull from the (I think), identitcal HRRR archives on Azure, and GCP, and so can be used more easily by users on those platforms.
