Oxford MIPAS meeting#108
12 December 06

Present

Instrument Status [Prev] [Next]
MIPAS has just finished a couple of months of nominal mode observations 2 orbits on followed by 3 orbits off (intended to be tested as an input for ECMWF data assimilation). Various other observations (including AE mode) planned until the end of the year.

November Monthly Report (JW) [Prev] [Next]
MIPAS monthly report for November is now available [Summary]
Full report downloadable from http://earth.esa.int/pcs/envisat/mipas/reports/monthly/

RR27 Retrieval (AD) [Prev] [Next]
Prepared poster for ACVE-3 meeting and wrote up as paper.

Precision Validation (CP) [Prev] [Next]
Using comparisons of pairs of MIPAS retrievals at locations where orbits intersect to see how the observed standard deviation compares with the predicted variability from the retrieval covariance.

TES Radiance Comparisons (CW) [Prev] [Next]
Continuing with comparison of MIPAS and TES limb radiance spectra from Jan 28 2005 using regions where the MIPAS bands and TES filters overlap

CO Retrievals (JW) [Prev] [Next]
Continuing with a joint retrieval of CO and vibrational temperature using RFM being used in non-LTE mode as a forward model within IDL retrieval program

Cloud Parameters (JH) [Prev] [Next]
Attempting to retrieve Cloud Top Height, Cloud Extinction and/or cloud top temperature using a pair of adjacent sweeps (the cloud top being in the FOV of the upper sweep) and a single microwindow 960-961cm-1 (most transparent region of MIPAS spectrum)

Mesospheric Spectra (LMV) [Prev] [Next]
Analysing contents of MIPAS mesospheric spectra (52, 60 and 68km nominal altitudes). Having masked out the spectral points influenced by atmospheric lines, the resulting spectra can be used to examine the noise and radiometric offset.

ACVE-3 Workshop 4-7th Dec, Frascati [Prev]
