Sensitivities of modelled water vapour in the lower stratosphere: temperature uncertainty, effects of horizontal transport and small-scale mixing [PDF]
Atmospheric Chemistry and Physics, 2018 Water vapour (H2O) in the upper troposphere and lower stratosphere (UTLS) has a significant role for global radiation. A realistic representation of H2O is therefore critical for accurate climate model predictions of future climate change.

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 ...

Characteristics of gravity waves resolved by ECMWF [PDF]
Atmospheric Chemistry and Physics, 2014 Global model data from the European Centre for Medium-Range Weather Forecasts (ECMWF) are analyzed for resolved gravity waves (GWs). Based on fitted 3-D wave vectors of individual waves and using the ECMWF global scale background fields, backward ray ...

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

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.

Sudden Stratospheric Warmings [PDF]
Reviews of Geophysics, 2020 Abstract Sudden stratospheric warmings (SSWs) are impressive fluid dynamical events in which large and rapid temperature increases in the winter polar stratosphere ( ∼ 10–50 km) are associated with a complete reversal of the climatological wintertime westerly winds. SSWs are
