Atmospheric Observation Program JAL Environmental Affairs
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
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
Old Observation Program 1993~2005
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
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)
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

Comparison – CME & ASE Data Dec 08, 2005 Good Agreement with Precise Measurements
Routes - New Atmospheric Observation Project Actual Route flown and numbers of data obtained(Nov. ‘05~ Jan’07)
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
