MIPAS QWG15
ESRIN 23-25 Jan 2008
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

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
