• Satellite data validation: a parametrization of the natural variability of atmospheric mixing ratios.

  Authors:Alexandra Laeng, Thomas von Clarmann, Quentin Errera, Udo Grabowski, and Shawn HonomichlFrom:Atmospheric Measurement Techniques (Vol. 15, Issue 8) Peer-Reviewed

  Apr. 20, 2022158 words Brief article High-resolution model data are used to estimate the statistically typical mixing ratio variabilities of trace species as a function of distance and time separation. These estimates can be used to explain the fact that...

• Direct inversion of circulation and mixing from tracer measurements -- Part 1: Method

  Authors:Thomas von Clarmann and Udo GrabowskiFrom:Atmospheric Chemistry and Physics (Vol. 16, Issue 22) Peer-Reviewed

  Nov. 23, 2016251 words Brief article From a series of zonal mean global stratospheric tracer measurements sampled in altitude vs. latitude, circulation and mixing patterns are inferred by the inverse solution of the continuity equation. As a first step,...

• MIPAS IMK/IAA carbon tetrachloride (CCl.sub.4) retrieval and first comparison with other instruments

  Authors:Ellen Eckert, Thomas von Clarmann, Alexandra Laeng, Gabriele P. Stiller, Bernd Funke, Norbert Glatthor, et al.From:Atmospheric Measurement Techniques (Vol. 10, Issue 7) Peer-Reviewed

  July 28, 2017291 words Author abstract, Bri... MIPAS thermal limb emission measurements were used to derive vertically resolved profiles of carbon tetrachloride (CCl.sub.4). Level-1b data versions MIPAS/5.02 to MIPAS/5.06 were converted into volume mixing ratio...

• On the improved stability of the version 7 MIPAS ozone record

  Authors:Alexandra Laeng, Ellen Eckert, Thomas von Clarmann, Michael Kiefer, Daan Hubert, Gabriele Stiller, et al.From:Atmospheric Measurement Techniques (Vol. 11, Issue 8) Peer-Reviewed

  Aug. 10, 2018342 words Author abstract, Bri...

  The Michelson Interferometer for Passive Atmospheric Sounding (MIPAS) was an infrared limb emission spectrometer on the Envisat platform. From 2002 to 2012, it performed pole-to-pole measurements during day and...

• IMK/IAA MIPAS temperature retrieval version 8: nominal measurements.

  Authors:Michael Kiefer, Thomas von Clarmann, Bernd Funke, Maya García-Comas, Norbert Glatthor, Udo Grabowski, et al.From:Atmospheric Measurement Techniques (Vol. 14, Issue 6) Peer-Reviewed

  June 7, 2021560 words Article A new global set of atmospheric temperature profiles is retrieved from recalibrated radiance spectra recorded with the Michelson Interferometer for Passive Atmospheric Sounding (MIPAS). Changes with respect to previous...

• The middle atmospheric meridional circulation for 2002-2012 derived from MIPAS observations.

  Authors:Thomas von Clarmann, Udo Grabowski, Gabriele P. Stiller, Beatriz M. Monge-Sanz, Norbert Glatthor, and Sylvia KellmannFrom:Atmospheric Chemistry and Physics (Vol. 21, Issue 11) Peer-Reviewed
