• Superposition of gravity waves with different propagation characteristics observed by airborne and space-borne infrared sounders.

  Authors:Isabell Krisch, Manfred Ern, Lars Hoffmann, Peter Preusse, Cornelia Strube, Jörn Ungermann, et al.From:Atmospheric Chemistry and Physics (Vol. 20, Issue 19) Peer-Reviewed

  Oct. 7, 2020328 words Brief article Many gravity wave analyses, based on either observations or model simulations, assume the presence of only a single dominant wave. This paper shows that there are much more complex cases with gravity waves from multiple...

• Satellite observations of middle atmosphere gravity wave absolute momentum flux and of its vertical gradient during recent stratospheric warmings

  Authors:Manfred Ern, Quang Thai Trinh, Martin Kaufmann, Isabell Krisch, Peter Preusse, Yajun Zhu, et al.From:Atmospheric Chemistry and Physics (Vol. 16, Issue 15) Peer-Reviewed

  Aug. 9, 2016384 words Brief article Sudden stratospheric warmings (SSWs) are circulation anomalies in the polar region during winter. They mostly occur in the Northern Hemisphere and affect also surface weather and climate. Both planetary waves and...

• First tomographic observations of gravity waves by the infrared limb imager GLORIA

  Authors:Isabell Krisch, Peter Preusse, Stephen D. Eckermann, Manfred Ern, Felix Friedl-Vallon, Martin Kaufmann, et al.From:Atmospheric Chemistry and Physics (Vol. 17, Issue 24) Peer-Reviewed

  Dec. 18, 2017326 words Brief article 970LAtmospheric gravity waves are a major cause of uncertainty in atmosphere general circulation models. This uncertainty affects regional climate projections and seasonal weather predictions. Improving the representation...

• Mesoscale fine structure of a tropopause fold over mountains

  Authors:Wolfgang Woiwode, Martina Bramberger, Felix Friedl-Vallon, Florian Haenel, Erik Kretschmer, Isabell Krisch, et al.From:Atmospheric Chemistry and Physics (Vol. 18, Issue 21) Peer-Reviewed

  Oct. 30, 2018314 words Author abstract, Bri...

  We report airborne remote-sensing observations of a tropopause fold during two crossings of the polar front jet over northern Italy on 12 January 2016. The GLORIA (Gimballed Limb Observer for Radiance Imaging of the...

• 3-D tomographic limb sounder retrieval techniques: irregular grids and Laplacian regularisation

  Authors:Lukas Krasauskas, Jorn Ungermann, Stefan Ensmann, Isabell Krisch, Erik Kretschmer, Peter Preusse, et al.From:Atmospheric Measurement Techniques (Vol. 12, Issue 2) Peer-Reviewed

  Feb. 7, 2019227 words Author abstract, Bri...

  Multiple limb sounder measurements of the same atmospheric region taken from different directions can be combined in a 3-D tomographic retrieval. Mathematically, this is a computationally expensive inverse modelling...

• Characterization of blackbody inhomogeneity and its effect on the retrieval results of the GLORIA instrument

  Authors:Anne Kleinert, Isabell Krisch, Albert Adibekyan, Berndt Gutschwager, and Christian MonteFrom:Atmospheric Measurement Techniques (Vol. 11, Issue 7) Peer-Reviewed

  July 3, 2018178 words Author abstract, Bri...

  Limb sounding instruments play an important role in the monitoring of climate trends, as they provide a good vertical resolution. Traceability to the International System of Units (SI) via onboard reference or...

• Limited angle tomography of mesoscale gravity waves by the infrared limb-sounder GLORIA

  Authors:Isabell Krisch, Jorn Ungermann, Peter Preusse, Erik Kretschmer, and Martin RieseFrom:Atmospheric Measurement Techniques (Vol. 11, Issue 7) Peer-Reviewed

  July 23, 2018384 words Author abstract, Bri...

  Three-dimensional measurements of gravity waves are required in order to quantify their direction-resolved momentum fluxes and obtain a better understanding of their propagation characteristics. Such 3-D measurements...

• Orographically induced spontaneous imbalance within the jet causing a large-scale gravity wave event.

  Authors:Markus Geldenhuys, Peter Preusse, Isabell Krisch, Christoph Zülicke, Jörn Ungermann, Manfred Ern, et al.From:Atmospheric Chemistry and Physics (Vol. 21, Issue 13) Peer-Reviewed

  July 9, 2021513 words Article To better understand the impact of gravity waves (GWs) on the middle atmosphere in the current and future climate, it is essential to understand their excitation mechanisms and to quantify their basic properties. Here a...
