Level 4 data (shear probes)

Level 4 data (shear probes)

Level 4 data include the final dissipation estimates as time series, as well as indicators for the quality and accuracy of the estimates and additional derived parameters. Each dissipation estimate in level 4 corresponds to a spectrum in the level 3 data. Consequently, the level 3 and 4 TIME dimensions are similar. Parameter EPSI_FINAL is the final dissipation rate estimate, averaged of the selected estimates (using the QC flags) at that depth.
