Atmospheric, Oceanic & Planetary Physics, University of Oxford A Dudhia MIPAS ST6 Karlsruhe 18/19 Sep 2007 Page 2  Not yet enough ESA L2 data from reduced resolution mode to determine global trends (emphasis has been on local validation: usually UTLS1 mode, limited orbital coverage)  Instead, processed 1 day per month using Oxford L2 processor (MORSE), full and reduced resolution, Jul02 - Jul07  Uses same L1B/microwindows as ESA data, but optimal estimation algorithm, so small differences likely
