  2. Airborne Research Outline • U.S. Federal airborne science fleet • NSF C-130 & HIAPER • Anatomy of RAF • PACDEX • Tour C-130 & G-V

  3. Corporation of North American universities • mission = advance national interests & capabilities in atmospheric & related sciences. • NSF-funded research & development center • - missions in research, facilities, education, tech transfer UCAR NCAR EOL RAF Provides observing system tools for world-wide research Airborne research UCAR Mesa Lab Boulder CO

  4. Federal Airborne Science Fleet USNP-3 UND NASADC-8 NOAAP-3 NASAER-2

  5. Federal Airborne Science Fleet NASAWB-57 NASAProteus NASATwin Otter DOEG-1

  6. S. Dakota T-28 University Aircraft UND Citation Univ. Wyoming King-Air

  7. EOL Systems: Partnerships NCAR Electra - retired NRL P-3 now carries NCAR Doppler radar

  8. Atmospheric Boundary Layer Oceanography Air/Sea Interaction Cloud Physics Tropospheric Profiling Radiometric Measurements Atmospheric Chemistry Aerosol Measurements 10 Hours Endurance Range 3100 nm Max Operating Altitude 26,000 ft 23,000 lb (13,000 with max fuel) Electrical Power 90kVA @ 115 Vac 400 Hz; 21kVA @ 115Vac 60 Hz; 400A @ 28Vdc C130 Research Aircraft

  9. C-130 • basic instruments • adjustable configurations • investigator instruments

  10. HIAPERHigh-performance Instrumented Airborne Platform for Environmental Research Gulfstream-VModifications 2003 – 2005+missions: ProgSci 2005, T-REX 2006, PACDEX 2007

  11. HIAPER - performance Endurance 10 h Range 6,000 nm Air speeds 120 – 230 m/s Altitude Max 51,000 ft Payload 3,400 lb Crew 2 pilots + 8 sci Electrical Power • 20kVA @ 115/208 vac 400 Hz; • 21kVA @ 115 vac 60 Hz; • 5 kW @ 28 vdc

  12. RAF Strength: Great Staff

  13. Field Project Support RAF staff of 35 people: • project management scientists • software engineers • electrical & instrumentation engineers • aeronautical engineer • instrument technicians • aircraft mechanics • pilots & flight engineers • scientists • administration

  14. Data Systems, Software, Processing, and Archival tools for data display and analysis free! - http://www.eol.ucar.edu/raf/Software/

  15. RAF Field Projects Earlier projects: 2000 TOPSE – Greenland to Manitoba 1999 MAPS – Italy-Austria-Switzerland 1999 INDOEX - Indian Ocean 1998 SHEBA - Alaska

  16. PACDEX - tracking Asian dust plume

  17. = step descent/ascent profiles deviating to sample clouds (See next figures) PACDEX Japan-Japan Flight Russian Airspace JAPAN Possible plume 1 hr Get above plume During ferry to Sampling region Possible plume Hawaii Plume track determined by forecast (only one plume)

  18. PACDEX - wing store instruments • UHSAS = aerosol size distr 70 -1000 nm • CDP = cloud droplet probe, 2 - 60 µm • 2DC = cloud particle size distr & images ~100-1600 µm • SID-2H = cloud particle size distr & phase, 2 - 60 µm • RICE = supercooled cloud water • King = liquid water condensate (g m-3) • video = forward looking

  19. PACDEX – cabin2 – pilots1 – mechanic7 - science crew9 - instrument racks

  20. PACDEX - cabin instruments • state parameters (T, P, humidity) + winds • water vapor • ozone • CO = carbon monoxide • HARP = radiation (actinic flux + spectral irradiance ~0.4 - 2 µm) • CVI = cloud condensate (> 5 µm, cloud particle residuals) • CFDC (CSU) = ice nucleating aerosol particles • CCN = cloud condensation nuclei (~0.2 – 1% ss) • SP-2 = soot particles (>100 nm size & conc) • streakers + impactor = aerosol particle collectors for SEM analysis • RDMA = aerosol size distribution (10 – 150 nm) • CN = total particle conc. • GNI = giant nuclei impactor ( > 2 µm) • satcom = satellite telephone data communications • real-time display stations + Internet Relay chat more about PACDEX - http://www.eol.ucar.edu/projects/pacdex/
