This page details all the ADCP data channels and metadata required to utilize the structure function techniques to reliably determine turbulence kinetic energy dissipation rate estimates. These will be divided into essential and supplementary categories. The NetCDF benchmark format was designed with the goal of facilitating algorithm testing and verification. Minimum requirements for archiving will be discussed at later date.

Benchmark datasets: Velocity profilers

ATOMIX provides several benchmark datasets consisting of four processing levels.

  1. Raw timeseries
    • full resolution data in physical units
  2. Quality-controlled and segmented timeseries
  3. Structure function
  4. Dissipation [math]\displaystyle{ \varepsilon }[/math] estimates
    • dissipation estimates and corresponding quality parameter as time series
