  1. HARLIE Winds: Methods and Results M. Anderson, I. Andrus, C. Egbert, and T. Wilkerson Space Dynamics Laboratory Utah State University, Logan, UT 84341 (435) 797-9611 tdw@sdl.usu.edu Presentation for Working Group on Space-Based Lidar Winds Key West, FL January 23-25,2002 * Research Support: NPOESS, NASA, and SDL

  2. Research Objectives • Develop methods for HARLIE wind profiling • Compare HARLIE results with other wind sensors (sondes, GLOW, cloud imagery) • Refine techniques for data visualization and analysis • Develop mature HARLIE capability for wind lidar Cal/Val

  3. HARLIE Winds: Methods and Results Topics •  Wave image of HARLIE conical scan data: Curve-fit method •  Video imagery of cloud motions: Automated pattern recognition and tracking •  Automated data reduction for HARLIE scans • Plans and directions for future work

  4. Available Wind Data Comparisons (HARGLO-2) SkyCam (Automated) HARLIE (Automated) HARLIE (Manual) Sondes GLOW

  5.  HARLIE Wave Image  Wind direction and speed Lidar return as a function of HARLIE scan angle and time Curve fit (Manual/Automated) Phase  direction Amplitude  speed
