SE.OF Oceanographic observations — seawater level RW, minute value

Purpose: Assimilate and validate models and analyse extremes.

Unit: cm

Characteristics: Seawater level relative to the average water level of the year. An instantaneous reading per minute.

Design: Date, time, value, quality and depth of measurement.

Quality codes: Green (G) = Verified and accepted values. Yellow (Y) = Coarsely controlled values, suspicious or aggregated values. Orange (O) = Uncontrolled values

Limits: Both >0 and <0.

The mean water level of the year refers to an estimated/theoretical level based on observed annual averages since the start of measurements:

Delivery: Data is delivered in two different ways
1. Via a user interface where measurement series can be downloaded for one station at a time
Data can be downloaded for the last hour, last day or full time series except the last day(historical reviewed)
2. Via a machine-machine solution (Atom flow rate). Where the same series of measurements as above can be obtained
and also real-time data. These are the last hour’s readings. They can be retrieved for a measuring station
at a time or for all active measuring stations.
