The following casestudy provides a workflow perspective on the Grid ENabled Integrated Earth system modelling (GENIE) framework, which was introduced in Vol. 1. The three aims in constructing the framework were; (i) the flexible coupling of Earth system components; (ii) to tune and run the resulting models on a wide variety of platforms, including the Grid; and (iii) to archive, query and retrieve the results. The component models incorporated into GENIE to date have been designed to be computationally inexpensive. This feature allows researchers using the framework to construct ensemble experiments to investigate long-term climatic trends or to conduct comprehensive parameter-space or climate sensitivity studies. GENIE also incorporates a full carbon cycle which makes it particularly suitable for recreating paleo-climates spanning the full ice-core record. The framework also has a role in simulating future climate change, including the response of slowly varying features of the Earth system, such as the deep ocean, sediment deposition and mineral weathering processes. The workflow description is split into four main areas. First is the task of
