Calling Sequence

import pyTMD.io
ds = pyTMD.io.IERS.open_dataset()

Source code

pyTMD.io.IERS.open_dataset(input_file: str | Path = PosixPath('/home/docs/.cache/pytmd/opoleloadcoefcmcor.txt.gz'), chunks: int | dict | str | None = None, **kwargs)[source]

Open Ocean Pole Tide ASCII files from [14, 15]

Parameters:

input_file: str or pathlib.Path: Ocean pole tide file
chunks: int | dict | str | None, default None: Coerce output to specified chunks
crs: str | int | dict, default 4326: Coordinate reference system
compressed: bool, default False: Input file is gzip compressed

Returns:

ds: xarray.Dataset: Ocean pole tide data
