These datasets contain the measurements collected on the same model of wave energy converter across four facilities during the Marinet2 Round Robin Testing Program. The involved infrastructures are University College Cork, University of Plymouth, University of Edinburgh and Centrale Nantes. The datasets consist of : - the PTO characterisation tests (only for Centrale Nantes) - the decay tests - the regular and irregular wave calibration tests without model - the model tests in regular and irregular waves The data is delivered in a compressed file which includes : - An excel file with the description of test conditions for each test, the channel lists and the list of exported variables for each test.   - A pdf file describing the model, moorings and wave gauges locations in the basin. - Sensors datasheets and calibration documents - A NetCDF file for each test containing : Array variables corresponding to the measurement channels. These array variables are named with the measurement channel names and have a variable attribute corresponding to their physical unit. For wave gauges, additional variable attributes are set for X and Y location in the wave tank. Global attributes to describe the wave conditions, the infrastructure references, the basin dimensions… They are listed in the excel file.
