, outfnprefix, startdate, timestep, n_timesteps, shape, metadata, n_ens_members=1, incremental=None, **kwargs)#

Initialize a netCDF forecast exporter. All outputs are written to a single file named as ‘<outfnprefix>’.

  • outpath (str) – Output path.

  • outfnprefix (str) – Prefix for output file names.

  • startdate (datetime.datetime) – Start date of the forecast.

  • timestep (int) – Time step of the forecast (minutes).

  • n_timesteps (int) – Number of time steps in the forecast this argument is ignored if incremental is set to ‘timestep’.

  • shape (tuple of int) – Two-element tuple defining the shape (height,width) of the forecast grids.

  • metadata (dict) – Metadata dictionary containing the projection, x1, x2, y1, y2, unit attributes (projection and variable units) described in the documentation of

  • n_ens_members (int) – Number of ensemble members in the forecast. This argument is ignored if incremental is set to ‘member’.

  • incremental ({None,'timestep','member'}, optional) –

    Allow incremental writing of datasets into the netCDF files.

    The available options are: ‘timestep’ = write a forecast or a forecast ensemble for a given time step; ‘member’ = write a forecast sequence for a given ensemble member. If set to None, incremental writing is disabled.


exporter – The return value is a dictionary containing an exporter object. This c an be used with to write datasets into the given file format.
