pvtend.compute_climatology(data_dir: str | Path, output_dir: str | Path, years: Sequence[int], variables: Sequence[str] = ['u', 'v', 'w', 't', 'pv', 'z', 'q'], per_month: bool = True, engine: str = 'netcdf4') → list[Path]

Compute per-variable per-month hourly climatology.

Accumulates hourly data from monthly ERA5 files, averages over years, then applies Fourier smoothing.

Parameters:

• data_dir – Directory with ERA5 monthly NetCDF files.

• output_dir – Where to write climatology files.

• years – Years to include in the climatology.

• variables – Variable names to process.

• per_month – If True, output one file per (variable, month).

• engine – NetCDF engine.

Returns:

List of output file paths.
