  1. Atmospheric Observation Program JAL Environmental Affairs

  2. Introduction (in Ancient Days) ?

  3. Observation by Airplane • Limited Data • Validation for Model Transport • Validation for Satellite CO2 Observation • To understand Global Carbon Cycle Commercial Airliner High Frequency Severe Restriction Chartered Aircraft Flexibility High Cost

  4. Old Observation Program 1993～2005 • Collaborative Activity of ・ MRI (Meteorological Research Institute） ・ JAL Foundation ・ JAL • Measurement of GHG (CO2､CH4､CO) concentration • Between Japan and Australia • Alt 9～13 km（12 Points） • Twice per month • 747 Classic

  5. Old Observation Program 1993～2005

  6. Old Observation Program 1993～2005 Observation route and pointsCO2 concentration in upper atmosphere Result: ● Continuous upward trend in every latitude ● Annual zigzag caused by CO2 absorption by photosynthesis process in summer and CO2 emission from fallen leaves in winter. ● More land → Distinct zigzag in north hemisphere Refer to: http://www.jalfoundation.or.jp ● Observation Points

  7. New project from 2005 • in-situ CO2 measurement • Aircraft information from ARINC • New Equipment for Commercial Airliners • CME (Continuous CO2 Measurement Equipment) • Cruise （Every 1 Minute）, Ascent/Descent (Every 10 Sec) • ASE (Improved Automatic Air Sampling Equipment)

  8. New project from 2005 • Collaborative Activity of ・ MRI (Meteorological Research Institute） ・ Tohoku Univ. ・ JAXA (Japan Aerospace Exploration Agency) ・ NIES (National institute for Environmental Studies) 　・ Jamco ・ JAL Foundation ・ JAL • Measurement of GHG (CO2, CH4, CO + N2O, H2, SF6, 13C/12C, 18O/16O ) • Route： JAL Route（Australia, Asia, North America, Hawaii, Europe etc) • 747-400, 777-200 International Airplane

  9. New Atmospheric Observation Project （2005～） 12 Titanium Flasks ASE ARINC Latitude, Longitude, Altitude, GRD Speed, Air Temp etc. CME Size: 570H*320W*255D Weight: 25Kg

  10. All Flight above 2000ft Horizontal Distribution Vertical Distribution Vertical Distribution 2000ft 2000ft 600H Flight (2month)Download(Std Gas, Drier) CME Measurement

  11. New Atmospheric Observation Project （2005～） EMI (Electromagnetic Interference) Test Low Pressure Test

  12. STC (Supplemental Type Certificate)

  13. ASE Pump CME FWD System Installation – 747-400 air conditioning duct

  14. Air Sample Port CME Installation FWD Cargo System Installation – 777-200

  15. Airplanes equipped with New Observation Unit ASE and CME 747-400 CME 777-200 JA703J：Nov. ‘06～ JA8917：Nov. ‘05～ JA707J：Oct. ‘06～ JA8921：Feb. ’06～ JA705J：Jun. ‘06～

  16. Comparison – CME & ASE Data Dec 08, 2005 Good Agreement with Precise Measurements

  17. Routes - New Atmospheric Observation Project Actual Route flown and numbers of data obtained（Nov. ‘05～ Jan’０７）

  18. One result from New Observation Project

  19. Conclusion • Developed new CME and improved ASE • Reliable and accurate data by CME and ASE • Numerous data from around the world • Collaboration with satellite observation • Validation for Model Transport • Expect to understand Global Carbon Cycle and to predict Global Warming precisely

  20. Thank you !!
