Overview

This export is available in DELFT-FEWS versions after 28-10-2009 (FEWS version 2009.02)

Exports data to NetCDF files which comply to the CF 1.4 standard.
More information about the cf standards can be found at: http://cfconventions.org/

There are six types of NetCDF-CF exports which can be defined:

Configuring the export

An example of the NETCDF-CF_PROFILE_MATROOS export can be found at NETCDF-CF_PROFILE. The only difference is that the exportType must be changed to NETCDF-CF_PROFILE_MATROOS.

The structure of the netCDF file which is created is shown below.
