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.
