Journal ArticleDOI
Implication of strongly increased atmospheric methane concentrations for chemistry–climate connections
TL;DR: In this article, numerical simulations with the chemistry-climate model (CCM) EMAC are performed, aiming to assess possible consequences of significantly enhanced CH4 concentrations in the Earth's atmosphere for the climate.
Journal ArticleDOI
Model simulations of atmospheric methane (1997–2016) and their evaluation using NOAA and AGAGE surface and IAGOS-CARIBIC aircraft observations
Peter H. Zimmermann,Carl A. M. Brenninkmeijer,Andrea Pozzer,Patrick Jöckel,Franziska Winterstein,Andreas Zahn,Sander Houweling,Sander Houweling,Jos Lelieveld +8 more
TL;DR: In this article, a general circulation model was applied to simulate the global atmospheric budget, variability, and trends of methane for the period of 1997-2016, using interannually constant CH4 a priori emissions from 11 biogenic and fossil source categories.
Journal ArticleDOI
Slow feedbacks resulting from strongly enhanced atmospheric methane mixing ratios in a chemistry–climate model with mixed-layer ocean
Laura Stecher,Franziska Winterstein,Martin Dameris,Patrick Jöckel,Michael Ponater,Markus Kunze +5 more
TL;DR: In this paper, the effect of CH 4 changes on the chemical composition of the upper stratosphere has been investigated and the results show that the response of the stratosphere adjusted temperatures driven by slow climate feedbacks is dominated by the increase in stratospheric water vapour and ozone.
Journal ArticleDOI
Methane chemistry in a nutshell – the new submodels CH4 (v1.0) and TRSYNC (v1.0) in MESSy (v2.54.0)
TL;DR: In this paper, a simplified approach to simulate the core of methane chemistry in form of the new Modular Earth Submodel System (MESSy) submodel CH4 is presented, which involves an atmosphericchemistry mechanism reduced to the sink reactions of CH4 with predefined fields of the hydroxyl radical (OH), excited oxygen (O( 1 D)), as well as photolysis and the reaction products limited to water vapour (H2O ).

Implication of extreme atmospheric methane concentrations forchemistry-climate connections
TL;DR: In this paper, numerical simulations with a chemistry-climate model (CCM) are performed aiming to assess possible consequences of significantly enhanced CH 4 concentrations in the Earth's atmosphere for the climate.
