Parameterizations as boundary objects on the climate arena

This paper analyses the relationship between field experimentalists and simulation modellers in meteorological research on the one hand, and how this is related to climate change as a common arena of concern on the other. Climate has become the central topic in meteorological research and it is imperative to link specific research problems to climate change in order to receive funding and attract talent. In addition, climate models have become gatekeepers for claims about climate change. Hence, active participation in climate modelling processes is valuable for all parties. Observational data are used in order to develop new components - so-called parameterizations - for the climate models and these novel components therefore emerge as important boundary objects. While they serve different purposes for experimentalists and modellers; in terms of translation processes, they also serve to connect these groups and reinforce their mutual dependence.
