Page now updated (8Oct07)Only 2 minor modifications (from QWG12)
SPREAD error (2nd deriv) reduced from 2% to 0.2%GAIN error (0th deriv) reduced from 2% to 1% for C and D bands

Oxford processor MORSE uses same L1B/microwindows as ESA data, but optimal estimation algorithm.
Oxford emphasis on long-term trends: processing 1 day/month, global coverage, preferably NOM mode.(also, since June 2007, routinely process all MIPAS NOM/UTLS1/MA mode data
http://www.atm.ox.ac.uk/group/mipas/L2OXF/ ESA emphasis on processing validation data: usually UTLS1 and limited area coverage - ‘orthogonal’ to Oxford requirements
Run MORSE to compare with ESA data from 14Jun05 and 22Jun05 (as shown at QWG13)
