Exports data to NetCDF files which comply to the CF 1.4 standard.
To indicate that data values are missing , NetCDF-CF exports use float value 9.96921e+036 by default. It is possible to change it by entering a different missing value (NaN or other) in the configuration files. Use option <exportMissingValue> in TimeSeriesExport module, and <missVal> in GeneralAdapter
More information about the cf standards can be found at: http://cfconventions.org/

An example of the NETCDF-CF_PROFILE export will be given here.

An example of the IdMapping used for the NETCDF-CF_PROFILE export will be given below.
Note that in the IdMapping of the parameters, the external name must match the variable names as used by the netcdf file exactly (case sensitive). The locations that are mapped refer to branch id's which are defined in the Branches.xml.
If the parameter has an entry in the standard name CF table, you can enter it in the externalQualifier1 attribute of the parameter. The value of this qualifier will be added as the standard_name attribute for this variable in the netcdf exported file.
