  1. HARGLO-3: Wind Intercomparisons During IHOP Geary Schwemmer, Bruce Gentry NASA/GSFC Tom Wilkerson USU

  2. International H2O Project (IHOP 2002) • Research Objectives: • Quantitative Precipitation Forecast • Convective Initiation • Boundary layer processes • Instrumentation • 7 May to 16 June 2002 • Southern Great Plains

  3. IHOP Homestead Site Wind Instruments • GLOW Collected over 210hrs of data. • HARLIE operated 24/7 • SKYCAM cloud-tracked winds • S-POL Doppler Radar • surface anemometer, GPS sondes (1-4 /day) • Sodar, MAPR, Umass FM-CW Radar • Transients: MIPS, DOW, X-POL, ELDORA, HRDL, WCR, Dropsondes

  4. HARGLO-3 Objectives • Statistical Comparisons of various wind measurements • Develop hybrid data products combining surface data with aerosol and molecular lidar data • Determine validity “windows” in time and space for various instruments

  5. Time-line of Homestead Wind Measurements: 43 days, 16 wind instruments

  6. HARLIE IHOP Data Products Wind Profiles Backscatter Profiles Boundary Layer Heights Cloud Fraction vs Height & Time

  7. HARGLO – 4+ • Increase & extend ground-based instruments • Focus on relating airborne to ground-based measurements and verifying sampling strategies • Help develop a validation plan for spaceborne Doppler wind lidars
