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://cf-pcmdi.llnl.gov/conformance/requirements-and-recommendations/1.4
There are six types of NetCDF-CF exports which can be defined:
- Time series (NETCDF-CF_TIMESERIES)
- Profiles (NETCDF-CF_PROFILE)
- Grids (NETCDF-CF_GRID)
- Time series (NETCDF-CF_TIMESERIES_MATROOS)
- Profiles (NETCDF-CF_PROFILE_MATROOS)
- Grids (NETCDF-CF_GRID_MATROOS)
Configuring the export
An example of the NETCDF-CF_TIMESERIES_MATROOS export can be found at NETCDF-CF_TIMESERIES. The only difference is that the exportType must be changed to NETCDF-CF_TIMESERIES_MATROOS.
The structure of the netCDF file which is created is shown below.
