Eric Simley and Andrew Scholbrock of NREL present a webinar on LiDAR, a remote sensing device used in wind energy applications. This webinar has two parts. Part I deals with the LiDAR measurement principles and Part II about Nacelle-Based LiDAR applications. Eric and Andy take turns to present this second webinar of the Wind Workforce Development series. They organized IEA Wind Task 32 Workshop at the NAWEA/WindTech 2019 Conference. The Task 32 aims to identify and mitigate barriers to the use of LiDAR for wind turbine and wind energy site assessment, power performance testing, loads and control, and in complex flows.
