Level 2 data (shear probes)

Level 2 data are the full resolution, cleaned and despiked parameters from level 1. The initial data set is subdivided in sections and labeled accordingly in the parameter SECTION_NUMBER with integers. Level 2 data is ready for estimating spectra. In addition to cleaned and despiked level 1 data channels, level 2 data comprises the additional parameter summarized in the table below. It is important that the platform speed with respect to water, as used in the dissipation estimates, is included in this level. Also note that the shear probe time series (and optionnaly acceleration and vibration) must be cleaned and filtered as needed at this level, and will not be altered further when estimating dissipation rates.
