  1. Atmospheric Chemistry with Large and Small UAS in the Arctic • James W. Elkins • NOAA Earth Systems Research Laboratory • Global Monitoring Division • The NOAA-Environment Canada UAS Arctic • Scoping Workshop • September 25, 2012

  2. Outline of Talk • Motivation and Introduction • Science: Transport & Ozone Depletion • Future Possibilities: ATTREX and SkyWisp UAS • Conclusions Arctic Sea Leads observed during GloPac by ACAM from Scott Janz NASA Goddard

  3. UAS used or proposed for NOAA Atmospheric Chemistry Apps

  4. Atmospheric Chemistry UAS Experiments

  5. Unmanned aircraft systems Chromatograph for Atmospheric Species (UCATS) In bay #25 of Global Hawk Box weighs 27 kg (60 lb.), 24.6 x 40.6 x 45.7 cm (9.7x16x18.1”), 45.6 liters. Inlet Pump (KNF model 627), and two gas cylinders (N2 carrier & reference gas) adds another 9 kg (20 lbs.) MeasuresO3once every 10 seconds (commercial unit 2B,Inc.) MeasuresN2O, SF6 every 70 seconds andCO, H2,CH4every 140 seconds. On board calibration. Also measures water vapor (Maycomm, LLC), relative humidity, and ambient temperature (Vaisala LTD. probe) once every second. New improved ozone and H2O instruments supported by NASA. Compounds in red are measured by NASA Aura Satellite Instruments.

  11. CLaMS Accumulated Ozone Loss since 1 Dec 2009

  12. NOAA SkyWisp UAS Configuration • Glider plus payload (3) • Ground Station (2) • GlideTerm Software • Trackable Antenna System • Glider Comms System • Manual RC System • Launching System • Launching Supplies Fred Moore, Co-I, with SkyWisp

  13. NOAA Aircore • U.S. Patent No. 7597014 (10/6/2009) by Pieter Tans NOAA/GMD • First design was 150 m x 1/4” SS tubing, Smaller now. • Weighs ~ 16 lbs. • Launched locally by balloon.

  14. Passive AirCore Sampling System 100,000 feet Fill Gas Captured profile

  15. CO2 Jan. 14, 2012 Jan. 15, 2012 SGP Tower

  16. Typical SkyWisp flight profile

  17. SkyWisp is produced by Southwest Research Institute

  18. Summary • Overflight of the Global Hawk over the GV during HIPPO/3 produced similar tracer-tracer relationships with structure. • Breakup of the polar vortex with low ozone during HIPPO/3 and GloPac was observed in filaments. Agreement of ozone loss between ozone loss and model simulation. • EC collaboration on Global Hawk during ATTREX with British (contact: Eric Jensen)? • EC Collaboration with SkyWisp in Boulder and Canada
