Presentation Transcript

  1. Profilers & Surface Gauges NE Corner of Stuart Hwy & McMillans • 2835-MHz Precip. Profiler: 0.3-18 km • 920-MHz Wind Profiler: 0.3-3 km • 50-MHz Wind Profiler: 2-8 km • Joss-Waldvogel Disdrometer • Two Rain Gauges ARM Site • 50-MHz Boundary Layer Radar: 0.3-6 km

  2. 2835-MHz Profiler • Vertical Beam (only) • Precipitation Mode (60 m Pulse) Reflectivity Doppler Velocity Velocity Variance

  3. 2835-MHz Profiler • Vertical Beam (only) • Cloud Mode (500 m Pulse) Reflectivity Doppler Velocity Velocity Variance

  4. 920-MHz Profiler • Vertical Beam (North or East) Reflectivity Doppler Velocity Velocity Variance

  5. 50-MHz Profiler • Vertical Beam (North or East) Reflectivity Doppler Velocity Velocity Variance

  6. Surface Disdrometer and Rain Gauges Disdrometer Reflectivity Disdrometer Rain Rate Rain Accumulations

  7. 50-MHz and 2835-MHz Spectra Air Motion Hydrometeor

  8. Observed D0 - ZDR • D0 Retrieved from profiler pair • ZDR Estimated from CPOL • Brandes et al. (2004): D0 = 0.171ZDR3 - 0.725ZDR2 + 1.479ZDR + 0.717 • Bringi et al. (2002): D0 = 1.81ZDR0.486 • D0-ZDR Regression: 1.38 ZDR0.547

  9. Vertical Air Motion 50-MHz profiler Estimate updraft and downdraft statistics during convection – we have multiple years of data to analyze

  10. 50-MHz Boundary Layer Radar – ARM site Low altitude mode (0 – 3 km)

  11. 50-MHz Boundary Layer Radar – ARM site High altitude mode (2 – 8 km)
