Domenico Taraborrelli

Understanding atmospheric oxidation of trace gases and its interaction with weather and climate by means of multiphase chemical kinetic modelling at global scale.

Kerstin Hartung

My name is Kerstin Hartung and by training I am a meteorologist and climate scientist. I have been employed with the DLR (in the group on Earth-System modelling) since May 1st and am mainly working for the ExaESM Pilot Lab. As part of Topic 1 I am working on porting the photolysis code of the MESSy model to GPUs. In Topic 2 we want to implement parallel and asynchronous writing of data in MESSy to speed up the simulation in another way.
