2 Atmospheric, Oceanic & Planetary Physics, University of Oxford A Dudhia MIPAS ST7 Salamanca 17-19 Mar 2008 Page 2  Oxford processor MORSE uses same L1B/microwindows as ESA data, but optimal estimation algorithm.  Routinely processing all ESA L1B consolidated spectra (available about 2 weeks after acquisition)  Now also processing NRT data (available ~ hours after acquisition) - only NOM mode pT, H2O and O3 http://www.atm.ox.ac.uk/group/mipas/L2OXF /

7 Atmospheric, Oceanic & Planetary Physics, University of Oxford A Dudhia MIPAS ST7 Salamanca 17-19 Mar 2008 Page 7 Comparison of NRT and “Off-Line’’ Data  Identical OXF L2 processing used for both  Since NRT data started on 19 Feb 08 and latest OFL data completed for 24 Feb 08, only 6 days overlap so far
