Observed versus simulated mountain waves over Scandinavia – improvement of vertical winds, energy and momentum fluxes by enhanced model resolution? [PDF]

Atmospheric Chemistry and Physics, 2017
Two mountain wave events, which occurred over northern Scandinavia in December 2013 are analysed by means of airborne observations and global and mesoscale numerical simulations with horizontal mesh sizes of 16, 7.2, 2.4 and 0.8 km.

Dynamics and composition of the Asian summer monsoon anticyclone [PDF]

Atmospheric Chemistry and Physics, 2018
This study places HALO research aircraft observations in the upper-tropospheric Asian summer monsoon anticyclone (ASMA) into the context of regional, intra-annual variability by hindcasts with the ECHAM/MESSy Atmospheric Chemistry (EMAC) model.

Chlorine partitioning in the lowermost Arctic vortex during the cold winter 2015/2016 [PDF]

Atmospheric Chemistry and Physics, 2019
Activated chlorine compounds in the polar winter stratosphere drive catalytic cycles that deplete ozone and methane, whose abundances are highly relevant to the evolution of global climate.

Wintertime Saharan dust transport towards the Caribbean: an airborne lidar case study during EUREC⁴A [PDF]

Atmospheric Chemistry and Physics, 2022
Wintertime Saharan dust plumes in the vicinity of Barbados are investigated by means of airborne lidar measurements. The measurements were conducted in the framework of the EUREC4A (Elucidating the Role of Cloud-Circulation Coupling in Climate) field ...

Slow feedbacks resulting from strongly enhanced atmospheric methane mixing ratios in a chemistry–climate model with mixed-layer ocean [PDF]

Atmospheric Chemistry and Physics, 2021
In a previous study the quasi-instantaneous chemical impacts (rapid adjustments) of strongly enhanced methane (CH4) mixing ratios have been analysed. However, to quantify the influence of the respective slow climate feedbacks on the chemical composition ...

Forschungsstandort Kap Verde: Ein faszinierendes Labor für Meeres- und Atmosphärenforscher im tropischen Atlantik [PDF]

, 2011
Die Existenz des globalen Klimawandels ist wissenschaftlich unumstritten und inzwischen auch in der öffentlichen Diskussion zu einem Allgemeinplatz geworden. Kaum ein Monat vergeht, ohne dass uns klimatische Hiobsbotschaften aus irgendeinem Teil der Erde
