This paper describes the content of the joint research project 'Development of LiDAR measurement techniques for the German offshore test site' and its first results. The objective is to develop reliable and standardised remote sensing techniques for various new applications in the wind energy community and to support other RAVE1 projects at the German offshore test site 'alpha ventus'. The first measurement campaign dealt with the comparison of wind parameters measured by common anemometry in a height of up to 103 m and LiDAR data measured up to 220 m height. The first results show very good agreement when the two techniques are compared as to wind speed, wind direction and power curve determination at a 5 MW wind turbine. The status of the development of a wind field scanner for nacelle-based LiDAR measurements is described and an outlook to the forthcoming work is given. A scanner device for nacelle-based LiDAR measurements is under development and will be used for wind field analyses required for improved simulation of wake loading and advanced control strategies assisted by inflow measurements. Moreover, LiDAR measurements will be used for the development of a new method for fast power curve measurements using high-frequency unsteady wind speed measurements.
