- wradlib.io.xarray.open_radar_mfdataset(paths, **kwargs)¶
Open multiple radar files as a single radar sweep dataset or radar volume.
stror sequence) – Either a string glob in the form
"path/to/my/files/*"or an explicit list of files to open. Paths can be given as strings or as pathlib Paths. If concatenation along more than one dimension is desired, then
pathsmust be a nested list-of-lists (see
xarray.combine_nestedfor details). (A string glob will be expanded to a 1-dimensional list.)
dict, optional) – Dictionary with keys given by dimension names and values given by chunk sizes. In general, these should divide the dimensions of each dataset. If int, chunk each dimension by
chunks. By default, chunks will be chosen to load entire input files into memory at once. This has a major impact on performance: please see the full documentation for more details 2.
None, optional) – Dimensions to concatenate files along. You only need to provide this argument if
combine='by_coords', and if any of the dimensions along which you want to concatenate is not a dimension in the original datasets, e.g., if you want to stack a collection of 2D arrays along a third dimension. Set
concat_dim=[..., None, ...]explicitly to disable concatenation along a particular dimension. Default is None, which for a 1D list of filepaths is equivalent to opening the files separately and then merging them with
**kwargs (optional) – Additional arguments passed on to
