satpy.cf.data_array module

Utility to generate a CF-compliant DataArray.

satpy.cf.data_array._handle_data_array_name(original_name, numeric_name_prefix)[source]
satpy.cf.data_array._preprocess_data_array_name(dataarray, numeric_name_prefix, include_orig_name)[source]

Change the DataArray name by prepending numeric_name_prefix if the name is a digit.

satpy.cf.data_array.make_cf_data_array(dataarray, epoch=None, flatten_attrs=False, exclude_attrs=None, include_orig_name=True, numeric_name_prefix='CHANNEL_')[source]

Make the xr.DataArray CF-compliant.

Parameters:

  • dataarray (xr.DataArray) – The data array to be made CF-compliant.

  • epoch (str, optional) – Reference time for encoding of time coordinates. If None, the default reference time is defined using from satpy.cf.coords import EPOCH.

  • flatten_attrs (bool, optional) – If True, flatten dict-type attributes. Defaults to False.

  • exclude_attrs (list, optional) – List of dataset attributes to be excluded. Defaults to None.

  • include_orig_name (bool, optional) – Include the original dataset name in the netcdf variable attributes. Defaults to True.

  • numeric_name_prefix (str, optional) – Prepend dataset name with this if starting with a digit. Defaults to "CHANNEL_".

Returns:

A CF-compliant xr.DataArray.

Return type:

xr.DataArray
