Grid refinement
===============

Demonstrate two-dimensional model output interpolation onto grids with
increasing spatial resolution. The leftmost panel shows the original data with
a spatial resolution of 1 km, and other panels show interpolated results.

    /home/docs/checkouts/readthedocs.org/user_builds/hyoga/envs/stable/lib/python3.12/site-packages/hyoga/open/example.py:29: FutureWarning: In a future version, xarray will not decode timedelta values based on the presence of a timedelta-like units attribute by default. Instead it will rely on the presence of a timedelta64 dtype attribute, which is now xarray's default way of encoding timedelta64 values. To continue decoding timedeltas based on the presence of a timedelta-like units attribute, users will need to explicitly opt-in by passing True or CFTimedeltaCoder(decode_via_units=True) to decode_timedelta. To silence this warning, set decode_timedelta to True, False, or a 'CFTimedeltaCoder' instance.
