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

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

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

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]
Atmospheric 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.

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

Retrieving the age of air spectrum from tracers: principle and method [PDF]
Atmospheric 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 stratospheric are deep stratospheric intrusions? [PDF]
Atmospheric Chemistry and Physics, 2014 Abstract. Preliminary attempts of quantifying the stratospheric ozone contribution in the observations at the Zugspitze summit (2962 m a.s.l.) next to Garmisch-Partenkirchen in the German Alps had yielded an approximate doubling of the stratospheric fraction of the Zugspitze ozone during the time period 1978 and 2004.

Tuning of a convective gravity wave source scheme based on HIRDLS observations [PDF]
Atmospheric Chemistry and Physics, 2016 Convection as one dominant source of atmospheric gravity waves (GWs) has been the focus of investigation over recent years. However, its spatial and temporal forcing scales are not well known.

How robust are stratospheric age of air trends from different reanalyses? [PDF]
Atmospheric Chemistry and Physics, 2019 An accelerating Brewer–Dobson circulation (BDC) is a robust signal of climate change in model predictions but has been questioned by trace gas observations.

Philosophical Transactions of the Royal Society of London. Series A: Mathematical, Physical and Engineering Sciences, 2002 The stratosphere is that part of the atmosphere which lies between ca. 10 and 50 km above the surface of the Earth and which contains the ozone layer. It is the seat of much interesting behaviour in terms of dynamics, radiation and chemistry, now revealed in detail by observations from modern space instruments, but still not completely understood ...
