This file describes the structure of the wave and roller properties data used in the paper "Energy dissipation in the inner surf zone: new insights from LiDAR-based roller geometry measurements", submitted to Journal of Geophysical Research: Oceans.
The dataset is composed of 4 .mat files, which require the MATLAB software. The description of the data structure is given below for every file of the datset.
This dataset is distributed under the Creative Commons Attribution 4.0 International license.

1) The complete dataset of wave and surface roller properties used to produce Figure 4 is stored as a structure in the .mat file called "Data_Figure4.mat". In the following, nb_waves is the number of waves (38) and nb_pos is the number of cross-shore positions (981).
