Add a quickstart notebook that builds a skew-T log-P diagram from the NOAA HRRR 48 hour forecast "virtual" dataset. It opens the dataset's pressure_level group (39 isobaric levels) from the staging STAC catalog, extracts a vertical profile at a lon/lat point via the Lambert Conformal projection, and renders the sounding with MetPy (temperature/dew-point curves, surface parcel path, CAPE/CIN, LCL, and wind barbs). Reading the virtual store requires the gribberish zarr codec (decodes the virtual GRIB chunk references) and zarr >= 3.2 (built-in scale_offset codec), plus metpy for the plot; these are added to pyproject.toml.

dynamical-catalog 0.7.0 now declares gribberish~=1.5.0 and zarr~=3.2 as runtime dependencies, so the virtual dataset's GRIB decoding and the scale_offset codec are pulled in transitively. Bump the floor to >=0.7.0 and drop the explicit gribberish and zarr pins that are no longer needed.

Use MetPy's .metpy accessor (quantify / unit_array) to pull units directly from each variable's CF `units` attribute instead of attaching hPa/degC/m-s by hand. The dataset already carries correct CF units on the pressure_level group, so this removes the manual unit bookkeeping.

going to wrap this into the official quickstart for this dataset. |
