Velocity point-measurements

Welcome to the velocity point-measurements subgroup!

This subgroup addresses best practices in obtaining [Turbulent kinetic energy dissipation] rate estimates from time series of velocities measured at a point in space. The best practices will address largely how temporal measurements are converted into spectral observations in the wavenumber (space) domain. Typically, these spectral observations are fitted over the inertial subrange using a model spectrum.

The subgroup will provide recommendations on data processing, quality control measures, and benchmark datasets to evaluate routines in any programming languages. These benchmark datasets will cover measurements affected by surface waves and near the bottom. Although some work has been done in obtaining these measurements from moored platforms, we will not be providing benchmark datasets at this time. However, appropriate references to existing literature are welcome.

Our recommendations are intended to be applicable to measurements irrespective of the manufacturer provided the data is of sufficient quality for resolving the turbulence subrange of turbulence.
