ClimGrass C – Grassland carbon dynamics in a changing climate
Climate changes and elevated CO2 have major impacts on biogeochemical cycles, which may in turn feed back on the climate system. ClimGrass-C is a new project that aims to assess effects of multiple levels of elevated CO2 and warming and of an extreme climatic event (combined drought and heatwave) on ecosystem carbon dynamics and their interactions with the water and nitrogen cycles. In particular, ClimGrass-C aims to (i) obtain response surfaces of ecosystem processes based on multistep changes of warming and elevated CO2, (ii) detect how such changes modify plant and soil responses to extreme climatic events (drought / heatwave), and (iii) identify if and how this extreme climatic event influences the ecosystem response to warming and elevated CO2, and a subsequent extreme event (legacy effects).
ClimGrass C is based on an experimental infrastructure at the AREC Raumberg-Gumpenstein.
ClimGrass C is funded by the FWF - Austrian Science Fund
