  1. Seasonal Variability of O3 and H2O in the UT/LS based on airborne SPURT measurements Marc Krebsbach, Gebhard Günther, Nicole Spelten, and Cornelius Schiller Research Centre Jülich GmbH, ICG-I, Germany m.krebsbach@fz-juelich.de 35th COSPAR Scientific Assembly, Paris, France, 20th July 2004 Seasonal Variability of Ozone and Total Water in the UT/LS - 1/11

  2. about SPURT (I) • determine state of UT/LS • improve theoretical understanding of governing processes • airborne measurements with Learjet 35A: Seasonal Variability of Ozone and Total Water in the UT/LS - 2/11

  3. about SPURT (II) >144 fl. hours Seasonal Variability of Ozone and Total Water in the UT/LS - 3/11

  4. winter autumn spring summer O3 in -space Seasonal Variability of Ozone and Total Water in the UT/LS - 4/11

  5. winter winter autumn autumn spring spring summer summer O3 in PV-space Seasonal Variability of Ozone and Total Water in the UT/LS - 5/11

  6. autumn winter spring summer H2O in PV-space Seasonal Variability of Ozone and Total Water in the UT/LS - 6/11

  7. O3 distributions in e--space autumn autumn autumn autumn autumn winter winter winter winter winter spring spring spring spring spring summer summer summer summer summer Seasonal Variability of Ozone and Total Water in the UT/LS - 7/11

  8. H2O distributions in e--space autumn winter spring summer Seasonal Variability of Ozone and Total Water in the UT/LS - 8/11

  9. autumn spring extent of extra-tropical mixing layer Seasonal Variability of Ozone and Total Water in the UT/LS - 9/11

  10. results from SPURT so far • probability density distributions: • trace gas distr.: most compact / correlated with PV • seasonal cycle of H2O and O3 in UT/LS is evident • distributions in the e--space • strong tracer gradients through TP (hor. & ver.) • humid LMS (>10 ppmv) • TST up to 50 K above TP • extra-tropical mixing layer: • ML follows TP • seasonally independent extent of significant tropospheric influence traceable up to 8–9 PVU Seasonal Variability of Ozone and Total Water in the UT/LS - 10/11

  11. thank you very muchfor youropen eyes and ears thanks Seasonal Variability of Ozone and Total Water in the UT/LS - 11/11
