Dataset for wave-by-wave particle tracking in the surf zone

<p>This dataset comprises 49 trajectories with 3D positions of buoyant tracers reconstructed from stereo camera imaging using two cameras and a standard triangulation process. The data is extracted from stereo image frames of the sea surface, captured at a rate of 30 frames per second. These images were collected between 15:13:00 and 17:18:59 UTC on September 7, 2019, near the island of Sylt, Germany.</p> <div>An appropriate coordinate system was used to better represent the tracer position time series for the analysis of tracers position, velocity and acceleration.&nbsp;</div> <div>Details about the coordinate system are provided in the associated manuscript and supporting information as well as in&nbsp;</div> <div><a title="https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2021GL095722" href="https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2021GL095722" target="_blank" rel="noopener noreferrer">https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2021GL095722</a></div> <div>&nbsp;</div> <div>The dataset is organized into four columns: the frame time [&micro;s]; the X coordinate [m], defining the horizontal position with the origin at the base of Pole 2 (see above referenced paper)&nbsp;and oriented shoreward; the Y coordinate [m], denoting the transverse position perpendicular to the direction of wave propagation ;&nbsp;</div> <div>and the Z coordinate [m], specifying the vertical position with the axis oriented upward.</div> <p>These coordinates were obtained using a triangulation algorithm and adjusted using a coordinate system transformation to yield a precise, physically meaningful representation of the trajectories. The data is provided in .mat (MATLAB) format</p>
