320838184 | MDU6SXNzdWUzMjA4MzgxODQ= | 2108 | Avoiding duplicate time coordinates when opening multiple files | 5442433 | closed | 0 | 7 | 2018-05-07T14:59:54Z | 2023-03-12T13:29:40Z | 2023-03-12T13:29:40Z | NONE | When opening multiple netCDF files with xr.open_mfdataset(nfiles), if the files have a duplicate time stamp (e.g. when they are a product of a restart and continue process) the final xarray dataset has duplicate time coordinates like, <xarray.DataArray 'time' (time: 39)> array(['2010-02-01T00:00:00.000000000', '2010-02-01T01:00:00.000000000', '2010-02-01T02:00:00.000000000', '2010-02-01T03:00:00.000000000', '2010-02-01T04:00:00.000000000', '2010-02-01T05:00:00.000000000', '2010-02-01T06:00:00.000000000', '2010-02-01T07:00:00.000000000', '2010-02-01T08:00:00.000000000', '2010-02-01T09:00:00.000000000', '2010-02-01T10:00:00.000000000', '2010-02-01T11:00:00.000000000', '2010-02-01T12:00:00.000000000', '2010-02-01T12:00:00.000000000', '2010-02-01T13:00:00.000000000', '2010-02-01T14:00:00.000000000', '2010-02-01T15:00:00.000000000', '2010-02-01T16:00:00.000000000', '2010-02-01T17:00:00.000000000', '2010-02-01T18:00:00.000000000', '2010-02-01T19:00:00.000000000', '2010-02-01T20:00:00.000000000', '2010-02-01T21:00:00.000000000', '2010-02-01T22:00:00.000000000', '2010-02-01T23:00:00.000000000', '2010-02-02T00:00:00.000000000', '2010-02-02T00:00:00.000000000', '2010-02-02T01:00:00.000000000', '2010-02-02T02:00:00.000000000', '2010-02-02T03:00:00.000000000', '2010-02-02T04:00:00.000000000', '2010-02-02T05:00:00.000000000', '2010-02-02T06:00:00.000000000', '2010-02-02T07:00:00.000000000', '2010-02-02T08:00:00.000000000', '2010-02-02T09:00:00.000000000', '2010-02-02T10:00:00.000000000', '2010-02-02T11:00:00.000000000', '2010-02-02T12:00:00.000000000'], dtype='datetime64[ns]') Coordinates: * time (time) datetime64[ns] 2010-02-01 2010-02-01T01:00:00 ... Is there a way to avoid this either while reading or afterwards by dropping the non unique time coordinates? |
