Jülich Exzellenzpreis 2022

Dr. Simon Rosanka receives the “Jülich Exzellenzpreis 2022” for his research on the hydroxyl radical (OH). The hydroxyl radical is the so-called “detergent of the atmosphere”, responsible for the atmospheric self cleaning potential from several pollutants. In his dissertation Dr. Rosanka explored the influence of oxygen-containing, volatile organic compounds on the composition of the atmosphere, making a significant contribution to understanding hydroxyl chemistry.

Utilising global chemical transport models and developing a detailed representation of liquid-phase chemical processes, he was able to quantify in particular the contribution of clouds as a sink for ozone in the troposphere.

The Bernd Rendel-Prize is awarded by the German Research Foundation (Deutsche Forschungsgemeinschaft, DFG) for conducting promising and original geoscientific research at the beginning of the researcher’s career. The DFG awards Simon Rosanka the Bernd Rendel-Prize 2021 for quantifying the contribution of clouds as a sink for tropospheric ozone and making a significant contribution to ensuring that organic acids in the troposphere are no longer underestimated. He achieved this by developing the Jülich Aqueous-phase Mechanism of Organic Chemistry (JAMOC), a detailed aqueous-phase oxidation scheme for oxygenated volatile organic compounds and implementing it into the scavenging submodel (SCAV) of MESSy.

Hella Garny (DLR) receives the WCRP/WWRP International Prize for Model Development 2020.

One of Hella’s model developments is the EMIL operation mode of EMAC . It is a dry dynamical core model set-up within the MESSy framework, denoted as ECHAM/MESSy IdeaLized (EMIL) model setup. EMIL is developed with the aim to provide an easily accessible idealized model set-up that is consistently integrated in the MESSy model hierarchy.

ABC/J Young Academics Award 2016

Charlotte Hoppe (FZJ) receives the ABC/J Young Academics Award 2016 for her Dissertation entitled “A Lagrangian transport core for the simulation of stratospheric trace species in a Chemistry Climate Model”.

The ABC/J Young Academics Award is granted by the Geoverbundes ABC/J for outstanding, innovative and interdisciplinary work at the beginning of a scientific carreer. Charlotte Hoppe’s work describes the coupling of the Lagrangian model CLaMS (Chemistry Lagrangian Model of the Stratosphere) with the chemistry-climate model EMAC.

Aviation Award 2014

Volker Grewe, Sigrun Matthes and coauthors receive the Aviation Award 2014 for their study on the “Reduction of air traffic contribution to climate change: A REACT4C case study”. The project REACT4C investigated trans-Atlantic air traffic and analysed, which routing changes were required to achieve a reduction in the air traffic’s contribution to climate change by combining a detailed climate-chemistry model (EMAC) and a detailed air traffic model (SAAM).
