OptionalcharacteristicCharacteristic values (gauge marks), present only when requested; an empty array for a series without marks.
OptionalcommentThe operator's note while the series is disturbed (see TimeseriesComment);
absent otherwise. Read it whenever a reading's state is commented.
OptionalcurrentOptionalendEnd of a forecast series' window: the last forecast instant (about four days ahead).
OptionalequidistanceOptionalgaugeGauge zero of a water-level series (absent on e.g. flow series).
OptionalstartStart of the series' window — on a forecast series (WV, Wasserstandsvorhersage)
the instant the forecast was issued, e.g. "2026-10-06T07:00:00+02:00". Absent on
measured series. Forecast series are listed in a station's timeseries only with
includeForecastTimeseries; their values come from timeseries.measurements(station, "WV") and have no current measurement (404).
The unit of every value of this series, as the API publishes it. Read it; never
assume it from the shortname: most W (water level) series are in cm, but canal
and reservoir gauges publish W in m+NN (metres above sea level) or m+PNP
(metres above the gauge zero) — 69 of 737 W series on 5 October 2026, e.g. MÜNSTER OW
at 56.54 m+NN. Q is usually m³/s, temperatures °C.
Metadata for one timeseries of a station (e.g. "W" water level, "Q" flow).
