Configuring the import

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

From 2021.01 it is possible to import NETCDF attributes as timeSeriesProperties into FEWS. This can be configured in the properties (see example below). Using the example config, the value of the NETCDF attribute ‘systemid’ will be imported as a timeSeriesProperty ‘rivieren2’.

Since 2021.02 it is also possible to export timeSeriesProperties as NETCDF attributes. You can find a config example here: https://publicwiki.deltares.nl/display/FEWSDOC/NETCDF-CF_GRID+Export

Since 2020.02 NETCDF-CF_TIMESERIES is able to import from the NC file that contains more than one location list.

For example, NC file contains water level and discharge and these two parameters are defined on different locations. NC file contains then two location lists.

Please note : to be able to read the NC with multiple location(station) lists, the location(station) variable must have the attribute :cf_role = "timeseries_id";
