pysteps.io.exporters.export_forecast_dataset#

pysteps.io.exporters.export_forecast_dataset(field, exporter)#

Write a forecast array into a file.

If the exporter was initialized with n_ens_members>1, the written dataset has dimensions (n_ens_members,num_timesteps,shape[0],shape[1]), where shape refers to the shape of the two-dimensional forecast grids. Otherwise, the dimensions are (num_timesteps,shape[0],shape[1]). If the exporter was initialized with incremental!=None, the array is appended to the existing dataset either along the ensemble member or time axis.

Parameters:

  • exporter (dict) – An exporter object created with any initialization method implemented in pysteps.io.exporters.

  • field (array_like) –

    The array to write. The required shape depends on the choice of the ‘incremental’ parameter the exporter was initialized with:

    incremental

    required shape

    None

    (num_ens_members,num_timesteps,shape[0],shape[1])

    ’timestep’

    (num_ens_members,shape[0],shape[1])

    ’member’

    (num_timesteps,shape[0],shape[1])

    If the exporter was initialized with num_ens_members=1, the num_ens_members dimension is dropped.
