  3. What we hope to do… • Investigating stratosphere-troposphere-intrusions (STI) using tropospheric emission spectrometer (TES) data, ozonesonde data and the GEM-Flexpart model. Ozonesonde GEM-Flexpart

  4. ICARTT-IONS06 What we hope to do… • Investigating stratosphere-troposphere-intrusions (STI) using tropospheric emission spectrometer (TES) data, ozonesonde data and the GEM-Flexpart model. Ozonesonde GEM-Flexpart

  5. ICARTT-IONS06 TES What we hope to do… • Investigating stratosphere-troposphere-intrusions (STI) using tropospheric emission spectrometer (TES) data, ozonesonde data and the GEM-Flexpart model. Ozonesonde GEM-Flexpart

  6. ICARTT-IONS06 TES What we hope to do… • Investigating stratosphere-troposphere-intrusions (STI) using tropospheric emission spectrometer (TES) data, ozonesonde data and the GEM-Flexpart model. Ozonesonde GEM-Flexpart • Incorporating new GEM-MACH air quality prediction model to study character of STI.

  7. GEM-Flexpart • GEM-v3.2.0, the Canadian forecast model, coving North America with 58 vertical levels. • Lagrangian particle dispersion model, Flexpart. 0.5x 0.5o resolution Both plots cited from Trevor’s draft for JGR

  8. Ozonesonde • balloon-borne instruments, GPS with EN-SCI model 2Z-ECC ozonesondes and Vaisala RS80 radiosonde. • Temporally dense ozonesonde launches (daily). 2x 1o resolution Usually late afternoons or nights

  9. TES • High resolution Fourier transform spectrometer (FTS) on Aura satellite. • launched 2004 July 15, ~705 km sun-synch orbit. • Nadir footprint: 5.3km x 8.3km. O3: Similar Worden, Bowman, Noone, et al. (2006). 2x 1o resolution Early mornings (~6-8) or late afternoons (~17-19)
