The Extratropical UTLS:Observations, Concepts and Future Directions
Community Workshop in BoulderOctober 19-22, 2009
Organizing Committee
Bill Randel, Laura Pan, Andrew Gettelman (NCAR)Ken Bowman (Texas A&M)Peter Hoor (MPI-Mainz)Valerie Thouret (CNRS, Lab d’Aerologie, Toulouse)
Background / objectives for this workshop:
• Synthesize key observations from aircraft, satellites, ....
- research aircraft: START08, SPURT, NASA, others- in-service aircraft: MOZAIC, CARIBIC, CONTRAIL- many satellite and ground-based data sets
• Current state of UTLS modeling (process, regional and global models)
• Highlight key uncertainties in understanding
• Identify specific future research needs (observations and models)
•Workshop attended by ~90 people.
Sampling from research aircraft
Also in-service aircraft: CARIBIC (170 flights), MOZAIC (>32,000 flights!)
Program: Overview talks, contributed talks and postersDynamical structure CCMval overview by Hegglin/Gettelman Tropopause Inversion Layer, Double TropopausesChemical structure overview by Hoor/Pan tropopause definitions, coordinates for placing parametersTransport and STE overview by Haynes START08, HIPPOChemistry and microphysics CARIBIC overview by Zahn; CONTRAIL measurements modeling – whole atmosphere models, high vertical resolution, high horizontal resolution models satellite – TES, CALIPSO, ….
Program (cont’d): Overview talks, contributed talks and postersLong-term variability MOZAIC overview by Thouret tropical broadening, tropopause rising Asian monsoonFuture missions DC3, PREMIER, MACPEX, PACE, HALO proposed projects
• Rapporteur groups led follow-on discussions for each session.
• Plans for SPARC Newsletter article, perhaps IGACtivities article, and likely a summary white paper.
