pangeo_fish.io.prepare_dataset(dataset, chunks=None, bbox=None, names=None)#

Prepares a dataset of a reference model. It renames some variables (see names), adds dynamic bathymetry and depth and broadcast lat(itude)/lon(gitude) coordinates.

Parameters:

  • dataset (xarray.Dataset) – The pre-opened dataset of the fields data

  • chunks (mapping, optional) – The initial chunk size. Should be multiples of the on-disk chunk sizes. By default, the chunksizes are {"lat": -1, "lon": -1, "depth": 11, "time": 8}

  • bbox (mapping of str to tuple of float, optional) – The spatial boundaries of the area of interest. Shoud have the keys “longitude” and “latitude”. If provided, it checks whether there is data available within the dataset for the area.

  • names (mapping of str to str, optional) – A dictionary that maps the three variables that correspond to the “TEMP”, “XE” and “H0” data. By default, the names align data from the Copernicus Marine Service with {"thetao": "TEMP", "zos": "XE", "deptho": "H0"}.

Returns:

ds (xarray.Dataset) – The post-processed dataset.
