Short summary
This study evaluates the impact of an enhanced sampling rate on turbulence measurements using the Vaisala WindCube v2.1 lidar profiler. A prototype configuration, sampling 4 times faster than the commercial setup, is compared to the commercial configuration, with reference measurements provided by a 2D sonic anemometer. The prototype lidar captures greater variance, resulting in turbulence estimates that are more closely aligned with the reference.

This study examines motion's impact on LOS turbulent velocity fluctuations measured by lidar profilers. Onshore tests used a mobile lidar (WindCube v2.1) on a hexapod, comparing it to a fixed lidar. RMSE was calculated to assess motion effects on turbulence. Results showed alignment, wind speed and amplitude as significant influences on RMSE. Motion frequency affected LOS velocity spectra but had limited impact on RMSE compared to other factors.

A novel data-driven method is proposed to design an optimal sensor network for the reconstruction of offshore wind resources. Based on unsupervised learning of numerical weather prediction wind data, it provides a simple yet efficient method for the siting of sensors, outperforming state-of-the-art methods for this application. It is applied in the main French offshore wind energy development areas to provide guidelines for the deployment of floating lidars for wind resource assessment.

The characterization of the turbulence intensity (TI) from profiling lidars measurements is still an active area of research. In this paper, a new method is proposed to derive TI from a WindCube v2.1 lidar. The new method allows for a reduction of TI estimation by a factor of more than 3 in comparison to a method commonly used in the wind energy industry. Moreover, a new configuration of WindCube v2.1 with a sampling rate four times higher than that of the commercial lidar is presented.

France aims for major offshore wind growth. We examined future climate impacts on wind, waves, and water levels. Results suggest that mean winds and waves may weaken, but extreme waves and sea levels will increase. These trends are nevertheless accompanied by strong model uncertainties. These findings are necessary for designing durable offshore wind farms in France and ensuring reliable energy production for decades to come.

Short summary
This study tested a two-lidar system to measure wind variations more accurately than traditional single-lidar methods. By comparing 30 days of measurements with a reference instrument, we found that the new approach better captures turbulence and reduces errors in both along- and cross-wind directions. The results show that it can provide more reliable ground-based wind measurements, supporting improved weather monitoring and wind energy assessments.
