From December 29th 2019 and February 8th 2020, Leice's floating wind lidar WindMast 350-MB got good scores during the test at sea early this year, with monthly system availability reaching up to 100% and MPDA(monthly post-processed data availability) reaching 98.58%~99.8%, even though the weather condition wasn't good as expected, which was overcast & raining for over half month, with max. wind speed over 17m/s. The WindMast 350-MB system has proved its reliability, stability and accurate lidar data analysis and processing ability under severe marine environment conditions.
