Impact of different Asian source regions on the composition of the Asian monsoon anticyclone and of the extratropical lowermost stratosphere [PDF]
Atmospheric Chemistry and Physics, 2015 The impact of different boundary layer source regions in Asia on the chemical composition of the Asian monsoon anticyclone, considering its intraseasonal variability in 2012, is analysed by simulations of the Chemical Lagrangian Model of the Stratosphere

The advective Brewer–Dobson circulation in the ERA5 reanalysis: climatology, variability, and trends [PDF]
Atmospheric Chemistry and Physics, 2021 The stratospheric Brewer–Dobson circulation (BDC) is an important element of climate as it determines the transport and distributions of key radiatively active atmospheric trace gases, which affect the Earth's radiation budget and surface climate ...

Lagrangian simulations of the transport of young air masses to the top of the Asian monsoon anticyclone and into the tropical pipe [PDF]
Atmospheric Chemistry and Physics, 2019 We have performed backward trajectory calculations and simulations with the three-dimensional Chemical Lagrangian Model of the Stratosphere (CLaMS) for two succeeding monsoon seasons using artificial tracers of air mass origin.

Potential of future stratospheric ozone loss in the midlatitudes under global warming and sulfate geoengineering [PDF]
Atmospheric Chemistry and Physics, 2021 The potential of heterogeneous chlorine activation in the midlatitude lowermost stratosphere during summer is a matter of debate. The occurrence of heterogeneous chlorine activation through the presence of aerosol particles could cause ozone destruction.

Lagrangian simulation of ice particles and resulting dehydration in the polar winter stratosphere [PDF]
Atmospheric Chemistry and Physics, 2019 Polar stratospheric clouds (PSCs) and cold stratospheric aerosols drive heterogeneous chemistry and play a major role in polar ozone depletion. The Chemical Lagrangian Model of the Stratosphere (CLaMS) simulates the nucleation, growth, sedimentation, and

Quantitative detection of iodine in the stratosphere
Proceedings of the National Academy of Sciences of the United States of America, 2020 Significance Aircraft measurements in the lower stratosphere indicate iodine is efficient at destroying ozone in the gas and particulate phases. Active iodine chemistry in the upper troposphere–lower stratosphere (UTLS) is the result of convective ...

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.

3-D tomographic limb sounder retrieval techniques: irregular grids and Laplacian regularisation [PDF]
Atmospheric Measurement Techniques, 2019 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 problem.

An ultrahot gas-giant exoplanet with a stratosphere [PDF]
Nature, 2017 Infrared radiation emitted from a planet contains information about the chemical composition and vertical temperature profile of its atmosphere. If upper layers are cooler than lower layers, molecular gases will produce absorption features in the ...
