  7. Intercomparison of Ozone Profiles FTIR Kiruna (& Izana): 7 (2) comparisons with MIPAS version 4.53 (before Nov. 13) around 20 km: MIPAS vmr too low (up to 0.8 ppmv) around 30 km: MIPAS vmr too large (up to 0.8 ppmv) MIPAS columns (integr. prof. >16 km): ~ 10% too large altitude assignment: alt. shift of ~1.5 km MIPAS VMR (p) agrees better than VMR (H) Groundbased FTIR Kiruna, AOID 191, A.

  13. Intercomparison of Ozone Profiles Groundbased LIDAR Andoya, AOID 9073, 360, K. Stebel, G. Hansen, Y. Orsolini et al.

  14. Intercomparison of Ozone Profiles LIDAR Lauder : 7 comparisons with MIPAS version 4.53 height assignment is reasonable good agreement O.H.P. / Alomar: 7 (6) comparisons with MIPAS version 4.53 good agreement above ~20 km D altitude: 1 - 2 km

  18. Intercomparison of Ozone Profiles O3 sonde Hohenpeissenberg H. Claude (DWD) AOID 158, J.-C. Lambert, V. Soebijanta et al.

  19. Intercomparison of Ozone Profiles O3 sondes Uccle: 34 comparisons with MIPAS version 4.53 before Nov. 13: error in height assignment: 1 - 2 km quantitative analysis in progress Hohenpeissenberg: 5 comparisons with MIPAS version 4.53 good agreement above ~18 km error in height assignment: 1 - 2 km O3 sonde Uccle, AOID 300, H.

  20. Intercomparison of Ozone Profiles MWR Payerne Y. Calisesi et al. (MCH) AOID 158, J.-C. Lambert, V. Soebijanta et al.

  21. Intercomparison of Ozone Profiles MWR Payerne Y. Calisesi et al. AOID 158, J.-C. Lambert, V. Soebijanta et al.

  22. Intercomparison of Ozone Profiles 72 comparisons MWR Payerne Y. Calisesi et al. AOID 158, J.-C. Lambert, V. Soebijanta et al.

  23. Intercomparison of Ozone Profiles 38 comparisons MWR Payerne Y. Calisesi et al. AOID 158, J.-C. Lambert, V. Soebijanta et al.

  24. Intercomparison of Ozone Profiles MWR Payerne: 110 comparisons! with MIPAS version 4.53 before Nov. 13: agreement above ~22 km D altitude: 1 - 2 km after Nov. 13: significant improvement good agreement MWR Payerne Y. Calisesi (MCH) AOID 158, V. Soebijanta, J.-C. Lambert et al.

  25. Conclusion Comparisons with MIPAS 4.53 (data from Oct. 24 onwards) using g.b. MWR, LIDAR, FTIR, and O3 sondes before Nov. 13: D altitude: 1 - 2 km < 20 km: MIPAS vmr too low >25 km: MIPAS vmr too large after Nov. 13: O3 sondes Uccle & MWR Payerne (110 comparisons !) : height assignment is reasonable much better agreement Quality of MIPAS O3 profiles is quite promising

  26. Outlook • A quantitative validation has to be perfomed • Data from MIPAS observations before Oct. 24 are needed • More than 1000 files with O3 profile data on CAL/VAL data base • Topics to be addressed: • day / night differences • latitudinal dependence • coincidence criteria: influence of different time and geolocation • other MIPAS products (species)
