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.
