clouddrift.datasets.gdp6h#
- clouddrift.datasets.gdp6h(decode_times: bool = True) Dataset[source]#
Returns the NOAA Global Drifter Program (GDP) 6-hourly dataset as a ragged array Xarray dataset.
The data is accessed from a public HTTPS server at NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML) accessible at https://www.aoml.noaa.gov/phod/gdp/index.php. It should be noted that the data loading method is platform dependent. Linux and Darwin (macOS) machines lazy load the datasets leveraging the byte-range feature of the netCDF-c library (dataset loading engine used by xarray). Windows machines download the entire dataset into a memory buffer which is then passed to xarray.
Parameters#
- decode_timesbool, optional
If True, decode the time coordinate into a datetime object. If False, the time coordinate will be an int64 or float64 array of increments since the origin time indicated in the units attribute. Default is True.
Returns#
- xarray.Dataset
6-hourly GDP dataset as a ragged array
