View source for NetCDF velocimeters format

This page provides an overview of the NetCDF format of benchmark dataset for instruments that measure velocities at a point in space e.g., [[Acoustic-Doppler Velocimeters|acoustic-Doppler velocimeters]] and [[Travel-time Velocimeters | travel-time velocimeters]] (MAVS). 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 dataset format for velocity point-measurements ==
ATOMIX provides several benchmark datasets consisting of four processing levels.
[[File:Benchmark adv netcdf.png|380px|thumb|Layout of NetCDF-4 benchmark dataset. The groupings are intended as checkpoints for algorithm testing.]]

# [[Level 1 data (velocity point-measurements)|Raw timeseries]]
#* full resolution data in physical units including quality-control flags
# [[Level 2 data (velocity point-measurements)|Quality-controlled and segmented timeseries]]
#* [[Detrending time series|Detrended]] and subdivided further in individual [[Segmenting datasets|segments]].
# [[Level 3 data (velocity point-measurements)|Spectral observations]]
#* raw and cleaned (if applicable) spectra
# [[Level 4 data (velocity point-measurements)|Dissipation <math>\varepsilon</math> estimates]]
#* dissipation estimates and corresponding quality parameter as time series
