The findings described in the following sections of this chapter are to a large extent based on an analysis of documents available to me at the institution where I work, i.e. in the Data Management department (DM) of the German Climate Computing Centre (DKRZ, Deutsches Klimarechenzentrum), or are part of websites of other institutions in the climate research community. Additional information about aspects of the research infrastructure in climate science comes from what I could glean from the literature and by receiving answers to a questionnaire from senior scientists working at six different institutes in teams conducting research or providing service(s) in this field. In the next sections, frequent reference is made to these information sources, and many of the diagrams and figures shown have been prepared by my colleagues and by the principal investigators of large research projects for a variety of purposes. The figures include depictions of workflows, organisational diagrams highlighting collaborative aspects and easy-to-grasp displays of pathways of information, data and scientific results within the research cycle.
