  1. Recent MIPAS L2 Data Retrieved at Oxford Anu Dudhia University of Oxford

  2. Oxford processor MORSE uses same L1B/microwindows as ESA data, but optimal estimation algorithm. • Aim to process entire MIPAS dataset • Current data being processed on 4 dual-CPU desktops in AOPP undergraduate practical lab (as background tasks) • Past data being processed on a 10-CPU cluster • Aim to complete first run around mid-2008 http://www.atm.ox.ac.uk/group/mipas/L2OXF/

  3. Temperature 65S-90S 10mb

  4. Ozone 90S-65S 10mb

  5. Temperature 20S-20N 10mb

  6. Water Vapour 20S-20N 10mb

  7. Nitrogen Dioxide 20S-20N 10mb

  8. Temperature 65N-90N 10mb

  9. Nitrogen Dioxide 65N-90N 10mb

  10. Chlorine Nitrate 65N-90N 10mb

  11. Ozone 65N-90N 10mb

  12. Conclusions • No obvious problems with recent MIPAS spectra (up to end of 2007) • Dec 2007 appears to have been unusually cold in the arctic throughout the stratosphere (strong vortex?) • Enhanced conversion of NO2  ClONO2, but ozone concentrations still normal
