Developing MAGICC on the basis of CMIP6 output: ice, ocean, the carbon cycle, permafrost and the atmosphere

This PhD research project will focus on the characteristics of the Earth Climate system as modelled by the CMIP6 suite of climate models. The specific focus area will be defined by the PhD candidate. The basic study object will be the CMIP6 ensemble model runs that will become available in the next years. The working horse will be the MAGICC climate model and refined or new parameterisations of those uncertainty ranges in Earth System responses (as seen in CMIP5 and CMIP6 models). For example, building a simplified carbon-cycle model that includes a nitrogen cycle. Alternatively, building a number of gas cycles that take into account different tropospheric OH, photolysis and other sinks for a wide array of greenhouse gases. The PhD candidate could also look at other areas of her/his interest that are part (or could become part) of the MAGICC model (see live.magicc.org). The MAGICC model is one of the primary tools to determine an emission scenarios likelihood to stay below 1.5C or 2C and was widely used in IPCC AR5. Strong modelling capabilities in Fortran and MATLAB are an advantage.

A/Prof Malte Meinshausen is the Director of the Australian-German College at The University of Melbourne and is affiliated with Potsdam Institute for Climate Impact Research, Germany. He holds a Ph. D. in "Climate Science & Policy", a Diploma in "Environmental Sciences" from the Swiss Federal Institute of Technology, and an M.Sc. in "Environmental Change and Management" from the University of Oxford, UK. Before joining the Potsdam Institute for Climate Impact Research (PIK) in 2006, he was a Post-Doc at the National Center for Atmospheric Research in Boulder, Colorado. He has been contributing author to various chapters in the Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC AR4). Until May 2011, he was leading the PRIMAP ("Potsdam Real-Time Integrated Model for probabilistic Assessment of emission Path") research group at PIK before relocating to Melbourne. Since 2005, he is a scientific advisor to the German Environmental Ministry related to international climate change negotiations under the UNFCCC. Since 2014, he investigates methods to derive future climate targets for Australia in the context of a Future Fellow ARC project.
