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

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

8 Ozonesonde  balloon-borne instruments, GPS with EN-SCI model 2Z-ECC ozonesondes and Vaisala RS80 radiosonde.  Temporally dense ozonesonde launches (daily). 2 x 1 o 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. Worden, Bowman, Noone, et al. (2006). 2 x 1 o resolution Early mornings (~6-8) or late afternoons (~17-19) O 3 : Similar
