Purpose: Observe the height of sea waves and improve wave models. Assimilation and validation of models.
Unit: Meters to 2 decimals.
Characteristics: Significant wave height is the average of the highest third of the waves over 30 minutes. Measurements are made from buoys near the coast and at sea.A value per hour.
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: >0

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.
