Instrument Status [Prev] [Next]

Some details on the Envisat Web-Site including Instrument Availability web-site

No recent news, but according to most recent announcement MIPAS should now (1st March) be starting its 2nd block of 3-days continuous operation.

L1 Data [Prev] [Next]

Some L1B data now available from ESRIN from MIPAS operations during Dec04/Jan05

Date	Orbit	Mode	No.Scans	Sweeps/Scan	Alt.Range

23JAN05	15165	UTLS2	215	11	12-42km
	*Filename indicates orbit 15136 but internal data is from 15137

[Plot] of geographical coverage
AB band often flagged bad at low altitude - apparently due to problems with clouds

L2 OFL Data [Prev] [Next]

H2O2 [Prev] [Next]

GRL paper on H2O2 retrievals from MIPAS about to be submitted.

Pressure Retrieval (IY) [Prev]

M.Phys project attempting to retrieve tangent pressure directly from spectrum by ratio of suitably chosen microwindows.

Final error analysis indicates accuracy of this method is, at best, of the order of 10% (and rather worse for higher altitudes), so probably not useful accuracy.
Now writing up M.Phys report

TES Comparisons (CW) [Prev] [Next]

Looking at TES nadir spectra from 22 Aug 04 over the ocean

Attempting joint retrieval of ocean surface temperature and O3 column
Note that O3 profile retrievals from IR spectra have been performed from IMG measurements: http://troposat.iup.uni-heidelberg.de/AT2/PIs/TG_1/Coheur_1.htm

ASSFTS-12 Workshop [Prev] [Next]

Atmospheric Science from Space using Fourier Transform Spectrometry, Workshop to be held in Quebec, 18-20 May 2005
