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.
