Wave parameters (in situ)

High-frequency wave parameters dataset The Wave parameters product is providing high-frequency wave measurements collected by in-situ instrumentation. The time series is provided as continuous hourly measurements. The output files are provided as point measurements at fixed coastal locations, characterizing local wave climate conditions. The data product also delivers comprehensive quality control flags following Copernicus Marine In Situ TAC standards. Detailed information on the included datasets and vocabularies can be found in the Product User Manual. Technical details The datasets are provided separately for each location in NetCDF format. Each file contains a time series of wave parameters, their corresponding quality control flags and additional metadata. Parameters This product includes time series of wave height, period, and direction derived from direct measurements of sea surface elevation, pressure, and current velocity profiles. The wave parameters included in the dataset are listed below. Variable Long Name Units VHM0 Significant wave height m VZMX Maximum wave height m VTGA Mean wave period s VMDR Mean wave direction degree VAVH Average wave height (1/3) m VH110 Average wave height (1/10) m VHZA Mean zero-crossing wave height m VTMX Maximum wave period s VTPK Peak wave period s VAVT Average crest period s VT110 Average wave period (1/10) s VPSP Peak spectral period s ECOD Error code dimensionless Data sources Platforms: Fixed benthic node Instruments: AWAC 600KHz (Acoustic Wave and Current Profiler) Data quality While underlying sensors provide high precision (e.g., velocity ±1%, pressure ±0.25%, heading ±2∘), the final accuracy of wave parameters (Hs, Tp, direction) is not a fixed value. It is strictly dependent on deployment depth, configuration, and the limitation that resolvable wavelengths must be ≥2× the horizontal cell separation. A comprehensive quality control (QC) procedure has been applied to the data, following international Quality Assurance of Real-Time Oceanographic Data (QARTOD) standards and best practices, consistent with Copernicus Marine In Situ TAC standards. Flags are assigned based on automated QC tests, including global range, regional range, spike detection, gradient analysis, and stationarity tests. Something about known issues: Data gaps may occur due to instrument failures, maintenance periods, or extreme weather conditions. Accuracy can be affected by biofouling on sensors, particularly for pressure-based measurements. Wave direction measurements may have reduced accuracy in low wave energy conditions.
