ncdata.iris module

Interface routines for converting data between ncdata and Iris.

Convert NcData to and from Iris Cube\s.

This uses the ncdata.dataset_like interface ability to mimic netCDF4.Dataset objects, which are used like files to load and save Iris data. This means that all we need to know of Iris is its netcdf load+save interfaces.

ncdata.iris.from_iris(cubes, **iris_save_kwargs)

Create an NcData from Iris cubes.

Behaves like an Iris ‘save’ operation.

Parameters:

• cubes (iris.cube.Cube, or iterable of Cubes) – cube or cubes to “save” to an NcData object.

• iris_save_kwargs (dict) – additional keys passed to iris.save() operation.

Returns:

ncdata – output data created from saving cubes

Return type:

NcData

ncdata.iris.to_iris(ncdata, **iris_load_kwargs)

Read Iris cubes from an NcData.

Behaves like an Iris ‘load’ operation.

Parameters:

• ncdata (NcData) – object to be loaded, treated as equivalent to a netCDF4 dataset.

• iris_load_kwargs (dict) – extra keywords, passed to iris.fileformats.netcdf.load_cubes()

Returns:

cubes – loaded results

Return type:

CubeList
