Abstract

Fine-scale wind measurements in the planetary boundary layer are required for understanding turbulence in complex terrain, flux of energy and aerosols, and severe weather events. The University of Colorado, Boulder (UCB), is developing an airborne Doppler lidar (ADL) system with five-fixed-direction beams to improve wind measurements in heterogeneous conditions. The five-fixed-beam system takes continuous radial wind velocity measurements at multiple angles including a dedicated nadir beam for high-resolution vertical measurements. Results of an ADL simulator, based on a large eddy simulation (LES) with 10 m vertical and horizontal resolutions, demonstrated that the five-beam system can reduce wind profile retrieval error due to turbulence by more than 40%, is less sensitive to restrictive design parameters, and can resolve planetary boundary layer 2D roll structures.
