  2. Discussion Outline IFEX 2006 • Goals • What we did well…what we need to work on HFP Research Activities • Tropical Storm Debby (SALEX; G-IV) • Hurricane Ernesto (SFMR Module; P-3) • Hurricane Helene (SALEX; P-3/G-IV) • Aerosonde update HFP Operational Activities • Synoptic Surveillance (Chris, Ernesto) • Doppler Winds (Ernesto, Helene) IFEX 2007

  3. IFEX 2006 • Goal 1 • Collect observations that span the TC lifecycle in a variety of environments (EMC): NASA/NOAA coordination (Debby, Helene)  • Goal 2 • Develop and refine measurement technologies that provide improved real-time monitoring of TC intensity, structure, and environment (NHC): SFMR Module (Ernesto); Doppler Winds (Ernesto, Helene)  • Goal 3 • Improve our understanding of the physical processes important in intensity change for a TC at all stages of its lifecycle (HRD): SALEX (Debby, Helene); Doppler Winds (Ernesto, Helene) 

  4. IFEX 2006 • What went well: • Pre-season discussions with TPC and EMC** • HFP pre-brief to NHC** • HFP director contacting NHC Hurricane Specialist before and during HRD deployments** • GMex pre-season ocean survey (EMC) • Debby-Ernesto (research to operational transition) • SFMR module (piggy-backed on the Ernesto landfall mission) • What do we need to work on: • “Off-season” discussions to focus on overlapping interests** • Communications during the hurricane season** • Debby-Ernesto type transitions **2005

  17. Hurricane Helene 060916

  18. Aerosonde UAV • Primary Objective • Fully demonstrate the Aerosonde platform Fully demonstrate the Aerosonde platform’s overall capabilities (including survivability) in a hurricane environment • Key Participants • NOAA HRD (Cione, Uhlhorn) • NOAA NHC (Sisko) • NASA (Turlington) • Aerosonde (Bale, Smith, Fowler, and Andrew) • Location and Duration • Key West Naval Air Station • 26 day demonstration project (01-26 September 2006) • Demo ended 26 September (weather & CoA) • Funding ($370 K) • NOAA HRD ($70 K) • NOAA NMAO/AOC ($100 K) • NASA ($200 K) • $80-100 K credit for 2007

  19. Aerosonde UAV • Insights from 2006: • Remote command and control at an operational center (NOAA/NHC) is possible and in fact was established at the onset of the 2006 Demo. • Second year of NASA/NOAA/Aerosonde coordination paid dividends: Building on 2005 Ophelia successful coordination, we were able to more easily (& efficiently) reach out to outside groups such as the NAVY, FAA & various media outlets as needed. • Underestimated the difficulty in getting a timely (and useful) US-based CoA. More work to do before 2007 season. • Overestimated mother nature (’06 no semblance to ’04 & ’05) • Given the last 2 lessons, it is highly recommended that multiple sites (1 domestic; 1 international) be established for any planned 2007 TC-UAS activity.

  20. Aerosonde UAV Outlook for 2007: • Key Participants • HRD, NHC, NASA, and Aerosonde • Proposed Locations & Duration • International: Barbados (proven NOAA P-3 deployment location; used for decades) • 45-day Early Season Demonstration (01 August - 15 September 2007) • Unlikely to encounter mission-restrictive airspace/clearance issues • Domestic: Key West NAS • 45-day Late Season Demonstration (15 September-31 October 2007) • Objectives • Fully demonstrate the Aerosonde platform’s overall capabilities and survivability in a hurricane environment (including ≤300m flying). • Demonstrate remote command and control capability at NHC, and possibly, using NOAA/NASA manned P-3 assets. • Utilize NOAA P-3 manned aircraft to enhance UAS-Hurricane missions (e.g. vertically stacked coincident data collection).

  21. Synoptic Surveillance • 2005 vs 2006 • 50 missions vs 7 missions • TS Chris • 02 August (1 mission) • no HRD scientists support (Aspen used for the 1st time) • Hurricane Ernesto • 27-30 August (6 missions) • all missions were HRD staffed

  22. Doppler Winds Hurricane Ernesto: 29/31 August (2 missions)Hurricane Helene: 18/20 September (2 missions)

  23. Real-time P3 Doppler-Winds analyses transmitted during 2006 Hurricane Season • 3 analyses on 29 August in Ernesto* • 6 analyses on 31 August in Ernesto* • 3 analyses on 18 September in Helene • 1 analysis on 19 September in Helene • 2 analyses on 20 September in Helene • *NWS-tasked NOAA P3 flights--Quality-Controlled Doppler radial data made available via ftp to EMC a few days after the flights

  24. 0.5 and 12 km Wind Analyses (m/s) Showing Easterly Shear over the center of Tropical Storm Ernesto on 29 August 2006 at 1520 UTC as it approached Florida 0.5 km 12.0 km

  25. Center SW Radial cross-section of total wind speed (m/s) outward from center toward SW in TS Ernesto on 31 August at 1700 UTC

  26. Real-time Doppler data Issues • Further automation is needed to start analysis jobs--we will explore complete or near-complete automation during this off-season • Further automation in determining systematic error corrections for radar pointing angle is needed • Network path from P3 to inside NWS (for both TPC and EMC) firewall still to be determined--need help on this from outside HRD • More reliable SATCOM communications will be needed to successfully send enough data to EMC • Further automation in transmitting files from P3 needed • Better pre-season training needed for those operating HRD Doppler QC software aboard the P3

  27. IFEX 2007 • Operations • Off-season discussions with TPC and EMC • Provide Doppler data to EMC (HRD) • Provide ocean data to EMC (HRD) • Validating Air Force SFMR data? (HRD) • Supporting Synoptic Surveillance mission planning (HRD) • Limited HRD resources to support a potentially substantial number of operational flight hours • Research • HRD: very limited P-3 flight hours/likely zero G-IV flight hours • Aerosonde, Genesis (weak systems), SALEX, Landfall/Inland decay
