Evaluation of modelled climatologies of O3, CO, water vapour and NOy in the upper troposphere – lower stratosphere using regular in situ observations by passenger aircraft

Autor: Yann Cohen, Didier Hauglustaine, Bastien Sauvage, Susanne Rohs, Patrick Konjari, Ulrich Bundke, Andreas Petzold, Valérie Thouret, Andreas Zahn, Helmut Ziereis

Evaluating the global chemistry models in the upper troposphere – lower stratosphere (UTLS) is an important step toward a further understanding of its chemical composition. The latter is regularly sampled through in situ measurements based on passe

Aviation-induced changes of atmospheric composition in the UTLS in the multi-scale Earth system model MECO(1)

Autor: Sigrun Matthes, Anna-Leah Nickl, Patrick Peter, Mariano Mertens, Patrick Jöckel, Helmut Ziereis, Theresa Harlaß, Andreas Zahn

Aviation is concerned by its climate effects which results from CO2 and non-CO2 effects, comprising NOx-induced changes of atmospheric ozone and methane. Here climate-chemistry models are required to advance our understanding on induced changes of re

Development and First Deployment of an Innovative Airborne δ13C(CH4) In Situ Measurement Setup

Autor: Paul Waldmann, Michael Lichtenstern, Friedemann Reum, Helmut Ziereis, Alina Fiehn, Michał Gałkowski, Christoph Gerbig, Andreas Fix, Anke Roiger

Recent atmospheric methane concentrations show an accelerated increase, but the contributions of the underlying emitters are poorly understood. Recording the stable carbon isotope ratio of methane (δ13C(CH4)) is a powerful tool for CH4 source attrib

The Indochina biomass burning (BB) season in springtime has a substantial environmental impact on the surrounding areas in Asia. In this study, we evaluated the environmental impact of a major long-range BB transport event on 19 March 2018 (a flight

Observations of microphysical properties and radiative effects of contrail cirrus and natural cirrus over the North Atlantic

Autor: Ziming Wang, Luca Bugliaro, Tina Jurkat-Witschas, Romy Heller, Ulrike Burkhardt, Helmut Ziereis, Georgios Dekoutsidis, Martin Wirth, Silke Groß, Simon Kirschler, Stefan Kaufmann, Christiane Voigt

Contrail cirrus constitute the largest radiative forcing (RF) component of the aviation effect on climate. However, the difference of microphysical properties and radiative effects between contrails, contrail cirrus and natural cirrus clouds are stil
