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).

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.

Ozone and Tracer Transport Variations in the Summer Northern Hemisphere Stratosphere [PDF]

, 2001
Constituent observations from the Upper Atmosphere Research Satellite (UARS) in combination with estimates of the residual circulation are used to examine the transport and chemical budgets of HF, CH4 and O3 in the summer Northern Hemisphere.

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.

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.

The stratosphere

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 ...

The potential role of stratospheric ozone in the stratosphere‐ionosphere coupling during stratospheric warmings [PDF]

Geophysical Research Letters, 2012
The recent discovery of large ionospheric disturbances associated with sudden stratospheric warmings (SSW) has challenged the current understanding of mechanisms coupling the stratosphere and ionosphere. Non‐linear interaction of planetary waves and tides has been invoked as a primary mechanism for such coupling.

Beyond Earth: Resilience of Quasi‐2D Perovskite Solar Cells in Space

Advanced Materials, EarlyView.
In the article (DOI: 10.1002/adma.202520433), Christoph Putz and co‐workers demonstrate rigid quasi‐2D perovskite solar cells operating in low Earth orbit, delivering stable power for more than 100 days under real‐space conditions. In‐orbit performance is correlated with extensive ground‐based thermal and proton‐irradiation studies on rigid and ...

Stratospheric predictability and sudden stratospheric warming events [PDF]

Journal of Geophysical Research: Atmospheres, 2009
A comparative study of the limit of predictability in the stratosphere and troposphere in a coupled general circulation model is carried out using the National Center for Environmental Prediction (NCEP) Climate Forecast System Interactive Ensemble (CFSIE).
