Because the floating LiDAR is the state-of-the-art remote-sensing technology using the laser-Doppler shifted effect, there is still no related international formal certification of the measured data. In this study, we conducted a series of tests and validation processes based on the three important stages before the commercial acceptance of the floating LiDAR released by not-for-dividend company Carbon Trust on Nov. 2013, including flume test, land test, harbor test, nearshore test, and offshore test. The objective is to verify the accuracy and reliability of the measured data. Also, the site and seasonal analysis of wind characteristics were investigated, including wind speed and wind direction. The results show the great capability and performance of the floating LiDAR and have a promising potential and influence to the offshore wind industry of Taiwan. The goal is to set the example for the series of tests and validation of floating LiDAR in Taiwan.
