Jul 2002 - Mar 2004: MIPAS operated at full resolution 0.025cm-1 sampling
ESA L2 products widely distributed and validated
MIPAS Data Availability
Jan 2005 - present: operated at 40% reduced resolution 0.0625cm-1 sampling
L1B spectra available, but routine ESA processing will not start until 2008

Oxford processor MORSE uses same L1B/microwindows as ESA data, but optimal estimation algorithm.
Standard ESA species p,T,H2O,O3,HNO3,CH4,N2O, NO2, plus additional molecules ClONO2, N2O5, CFC-11, CFC-12 and CO
Processed 1 day/month global coverage, preferably NOM mode, for long term trends Since 1st June 2007 process all MIPAS L1B spectra http://www.atm.ox.ac.uk/group/mipas/L2OXF/
