How stratospheric are deep stratospheric intrusions? LUAMI 2008 [PDF]

open access: yesAtmospheric Chemistry and Physics, 2016
Abstract. A large-scale comparison of water-vapour vertical-sounding instruments took place over central Europe on 17 October 2008, during a rather homogeneous deep stratospheric intrusion event (LUAMI, Lindenberg Upper-Air Methods Intercomparison). The measurements were carried out at four observational sites: Payerne (Switzerland), Bilthoven (the ...

El Niño Southern Oscillation influence on the Asian summer monsoon anticyclone [PDF]

open access: yesAtmospheric Chemistry and Physics, 2018
We analyse the influence of the El Niño Southern Oscillation (ENSO) on the atmospheric circulation and the mean ozone distribution in the tropical and subtropical UTLS region.

Observations of filamentary structures near the vortex edge in the Arctic winter lower stratosphere [PDF]

open access: yesAtmospheric Chemistry and Physics, 2013
The CRISTA-NF (Cryogenic Infrared Spectrometers and Telescope for the Atmosphere – New Frontiers) instrument is an airborne infrared limb sounder operated aboard the Russian research aircraft M55-Geophysica. The instrument successfully participated

Superposition of gravity waves with different propagation characteristics observed by airborne and space-borne infrared sounders [PDF]

open access: yesAtmospheric Chemistry and Physics, 2020
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 sources crossing each others ...

Fast transport from Southeast Asia boundary layer sources to northern Europe: rapid uplift in typhoons and eastward eddy shedding of the Asian monsoon anticyclone [PDF]

open access: yesAtmospheric Chemistry and Physics, 2014
Enhanced tropospheric trace gases such as CO, CH4 and H2O and reduced stratospheric O3 were measured in situ in the lowermost stratosphere over northern Europe on 26 September 2012 during the TACTS aircraft campaign.

Orographically induced spontaneous imbalance within the jet causing a large-scale gravity wave event [PDF]

open access: yesAtmospheric Chemistry and Physics, 2021
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.

Stratospheric ozone depletion [PDF]

open access: yesPhilosophical Transactions of the Royal Society B: Biological Sciences, 1991
Solar ultraviolet radiation creates an ozone layer in the atmosphere which in turn completely absorbs the most energetic fraction of this radiation. This process both warms the air, creating the stratosphere between 15 and 50 km altitude, and protects the biological activities at the Earth's surface from this damaging radiation. In

Retrieving the age of air spectrum from tracers: principle and method [PDF]

open access: yesAtmospheric Chemistry and Physics, 2019
Surface-emitted tracers with different dependencies on transit time (e.g., due to chemical loss or time-dependent boundary conditions) carry independent pieces of information on the age of air spectrum (the distribution of transit times from the surface).

How can Brewer–Dobson circulation trends be estimated from changes in stratospheric water vapour and methane? [PDF]

open access: yesAtmospheric Chemistry and Physics, 2022
The stratospheric meridional overturning circulation, also referred to as the Brewer–Dobson circulation (BDC), controls the composition of the stratosphere, which, in turn, affects radiation and climate. As the BDC cannot be directly measured, one has to
