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. Our recommendations are designed for measurements collected by any manufacturer, provided the data quality is sufficient for resolving the inertial subrange of the velocity spectra.

We will provide benchmarks for velocity measurements both impacted and unaffected by surface waves. These benchmarks will be a resource for the Ocean Mixing Community to evaluate routines in any programming language. These benchmarks will be limited to instruments fixed in space. We will nonetheless include appropriate references to the existing literature on handling moored instruments.
