Global Wind Demonstration Project GroundWinds –Brief Status of GW-NH and GW-Hawaii NOAA/NASA GTWS Collaboration –Draft Data Requirements –Instrument Synthesis and Analysis –Integrated Mission Design

GroundWinds Status Nov 1-2: 10 th GroundWinds Quarterly Review –Held at Michigan Aerospace Corporation (MAC) headquarters in Ann Arbor, MI –MAC analyzed initial performance limitations of GWNH –NH Lidar realignment issues solved, aerosol camera replaced, refurbished laser to be delivered, new data processing SW to eliminate earlier bias UNH to take new wind measurements to demonstrate photon recycling with these limited fixes Include new results in publication of Fall 2000 GroundWinds demonstration campaign More comprehensive improvements base-lined for GW Hawaii Additional science-directed campaigns planned for GWNH

University of HI Participation Investigate the utility of UV LIDAR wind profiles University of Hawaii has become GroundWinds partner University of Hawaii Role & Goals: –Oversee remote operation of GroundWinds-HI –Analyze atmospheric structures (troughs, jet streaks) –Analyze impact of terrain on gravity wave formation and turbulence –Construct tools for weather hazard mitigation (detection of CAT, flash flood index) –Create a state-of-the-art nowcast of momentum by ingesting LIDAR data into FSL’s Local Analysis and Prediction System (LAPS) –Use LAPS output as initial state for MM5 –Use LIDAR data to identify systematic forecast errors in NWP output –Port the Hawaii LAPS capability to AWIPS at the NWSFO –Establish active outreach program to introduce the technology to NWS staff, university, & primary/secondary school students in Pacific Region

Upcoming Events GroundWinds-NH mini-campaign Bartlett, NH GroundWinds Quarterly, March 6-8, Hawaii Lidar Winds Working Group, Jul 15-17, N. Conway, NH GroundWinds-HI validation campaign (TBD)
