  1. Mesoscale Breakout Session NSF Facility User’s Workshop June 2009 ~30 participants Good spectrum of students, NCAR, university, and NSF representation No consensus recommendations, just good discussion

  2. Some (but not all) interesting mesoscale phenomena that need more observations • Hurricanes • Flux measurements in extreme conditions (>50 m/s) • Sea spray measurements • Enhanced Observations • Towed drone (not in DP) • Rapid-fire (km scale)dropsondes (enhancement to DP)

  3. Complex Terrain • Orographic precipitation, moist processes, wave dynamics • Enhanced Observations • “More” mobile and polarimetricradars (enhancement to DP) • Remote sensing of wind (enhancement to DP) and thermodynamics (new to DP) from aircraft • Particle size distribution via polarimetric radar (available, but challenging) and disdrometers (new to DP)

  4. Other topics of interest • Winter weather • Latent heating in tropical cyclogenesis • Improved microphysics, surface & boundary layer parameterizations in mesoscale modeling • Issues in mesoscale data integration, assimilation, and analyses

  5. Multi-year field campaigns • Do we need longer-term mesoscale observations (i.e. multiple year field campaigns)? • Advantages: • Increased sample size • Increased probability of detection • Disadvantages: • Resource commitments • NSF Mission of basic research vs. long-term monitoring

  6. Observational Wish-list • High density up & down soundings (potential trade-off in # of obs vs. platform & expendable cost/accuracy) • Multiple dual-polarimetric, phased-array, mobile radars • UAVs • Surveillance radar on DP aircraft • Dropsonde system on King Air (A10?) • Scanning water vapor DIAL (3D moisture) • 3D temperature?
