TL;DR: In this paper, an optimal estimation-based method is presented to infer abundances of atmospheric species from limb infrared emission spectra using the Michelson Interferometer for Passive Atmospheric Sounding (MIPAS) onboard the Envisat research satellite.
Journal ArticleDOI
Retrieval of temperature, H 2 O, O 3 , HNO 3 , CH 4 , N 2 O, ClONO 2 and ClO from MIPAS reduced resolution nominal mode limb emission measurements
T. von Clarmann,Michael Höpfner,Sylvia Kellmann,Andrea Linden,S. Chauhan,Bernd Funke,Udo Grabowski,Norbert Glatthor,Michael Kiefer,T. Schieferdecker,G. P. Stiller,Stefan Versick +11 more
TL;DR: In this paper, the MIPAS reduced spectral resolution nominal mode limb emission measurements outperform retrievals from respective full spectral resolution measurements both in terms of altitude resolution and precision.
Observed temporal evolution of global mean age of stratospheric air for the 2002 to 2010 period
Gabriele Stiller,T. von Clarmann,Florian Haenel,Bernd Funke,Norbert Glatthor,Udo Grabowski,Sylvia Kellmann,Michael Kiefer,Andrea Linden,Stefan Lossow,Manuel López-Puertas +10 more
TL;DR: In this paper, an extensive observational data set, consisting of more than 106 SF6 vertical profiles from MIPAS measurements distributed over the whole globe has been condensed into monthly zonal means of mean age of air for the period September 2002 to January 2010, binned at 10° latitude and 1-2 km altitude.
Journal ArticleDOI
Downward transport of upper atmospheric NOx into the polar stratosphere and lower mesosphere during the Antarctic 2003 and Arctic 2002/2003 winters
Bernd Funke,Manuel López-Puertas,Sergio Gil-Lopez,T. von Clarmann,Gabriele Stiller,Herbert Fischer,Sylvia Kellmann +6 more
TL;DR: In this article, the Michelson Interferometer for Passive Atmospheric Sounding (MIPAS) was used to measure upper stratospheric and mesospheric NOx enhancements in the Southern Hemisphere (SH) polar vortex from May to August 2003.
Journal ArticleDOI
Observation of NO(x) Enhancement and Ozone Depletion in the Northern and Southern hemispheres after the October-November 2003 Solar Proton Events
Manuel López-Puertas,Bernd Funke,Sergio Gil-Lopez,T. von Clarmann,Gabriele Stiller,Michael Höpfner,Sylvia Kellmann,Herbert Fischer,Charles H. Jackman +8 more
TL;DR: In this article, the Michelson Interferometer for Passive Atmospheric Sounding (MIPAS) observations of NO(x) (NO+NO2) and O3 of the period from 25 October to 14 November 2003, covering both the summer (daylight) and winter (dark) polar regions during an SPE.
