nctoolkit.DataSet.add

DataSet.add(self, x=None, var=None)

Add to a dataset This will add a constant, another dataset or a netCDF file to the dataset. nctoolkit will automatically determine the appropriate comparison required.

Parameters

  • x (int, float, DataSet or netCDF file) – An int, float, single file dataset or netCDF file to add to the dataset. If a dataset or netCDF file is supplied, this must have only one variable, unless var is provided. The grids must be the same.

  • var (str) –

    A variable in the x to use for the operation

    Examples

  • ------------ –

  • you wanted to add 10 to all variables in a dataset (If) –

  • would do the following (you) –

  • ds.add(10) (>>>) –

  • add the values in a dataset ds2 from a dataset ds1 (To) –

  • would do the following –

  • ds1.add(ds2) (>>>) –

  • in the datasets must match. Addition will occur in matching timesteps in ds1 and ds2. If there is only 1 timestep in ds2 (Grids) –

  • then –

  • data from that timestep will be added to the data in all ds1 time steps. (the) –

  • the data from another netCDF file will work in the same way (Adding) –

  • ds1.add("example.nc") (>>>) –
