Abstract
It is required to establish cost-effective wind observation methods for installing offshore wind farms near the coastline. In a wind measurement campaign at three coastal sites in Akita prefecture, we installed three types of equipment on the coast: a meteorological mast, a vertical Doppler LiDAR, and a scanning Doppler LiDAR targetted at 2 km offshore. This method is cost-effective because no marine construction is involved, which also implies easy access for maintenance. In a preliminary verification study, the scanning Doppler LiDAR was found to satisfy accuracy thresholds for comparison against meteorological masts. We are proceeding with analysis toward the establishment of measurement methods and the elucidation of wind conditions in coastal areas.
