Hannes Keck
I am a PhD student studying greenhouse gas fluxes from agricultural ecosystems. Currently, my research focuses on developing and testing a relaxed eddy accumulation (REA) system. This system is capable of measuring carbon dioxide, nitrous oxide, methane and water vapour fluxes at a field scale and over complete agricultural seasons. The combination of the REA system, manual chamber measurements as well as footprint modelling will help us understand the spatial and temporal heterogeneity of greenhouse gas fluxes and how driving variables influences these patterns.
