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

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

An example of the IdMapping used for the NETCDF-CF_TIMESERIES export will be given below. In this example, the mapped locations correspond to the locations of the locatiesSet as defined above in the ExportNetcdf_Timeseries.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.
