Science Objectives
Low pass of Rockies- Flt 2005-12-07
• Characterize the dynamical structure of the extratropical tropopause in and around the subtropical jet
• Identify the chemical transition from the troposphere to stratosphere across the extratropical tropopause.
• Investigate the irreversible STE & mixing produced by multiple scale dynamical processes

• Four successful flights (7-9 hour each, out of 6 planned)
• Measurements: O3, H2O, CO, in addition to
meteorological parameters (and other possible tracers such as CN)
• Near real time satellite data via collaboration with AIRS science team
• Sampled several cases of stratospheric intrusion
• Obtained information on mixing and STE• Valuable data for AIRS ozone validation

Status of Data and Data Analyses
• Ozone data became available during the experiment. Intercomparison with CMDL ozonesonde show excellent agreement.
• Initial analyses and comparison with satellite data, meteorological analyses data have been carried out
• Water vapor preliminary data became available ~ 2 weeks ago, further calibration in progress
• CO data is still under Q/C verification• Trajectory analyses in progress

Summary
Results from the START experiment
• Demonstrated the capability of HIAPER in UTLS studies
• Initial data provided good validation for the satellite retrievals
• Sampled multiple cases of stratospheric intrusions. Characterization of the air mass in the region of intrusion using tracer-tracer correlation and trajectory model is in progress
