Benchmark datasets for ADCP structure function

This page provides an overview of the NetCDF format of benchmark dataset for instruments that measure velocity profiles e.g., acoustic-Doppler current profilers from diverse suppliers and models.

Benchmark datasets: Velocity profilers

ATOMIX provides several benchmark datasets consisting of four processing levels.

1. Raw timeseries
   • full resolution raw measurements in physical units, including ancillary parameters used to quality-control observations (e.g., amplitudes and correlations). Note: instrument-specific binary data is not included.
2. Quality-controlled timeseries
   • full resolution cleaned measurements from level 1
3. Structure function
   • calculated structure function parameters
4. Dissipation [math]\displaystyle{ \varepsilon }[/math] estimates
   • dissipation estimates and corresponding quality control parameter as time series

Datasets available

Selection and preparation of benchmark datasets are a work in progress! These benchmark datasets will cover a range of marine environments, background stratification and flow fields.
