In this poster we present an overview of our approach to researching the information infrastructure for weather and climate data in the UK, which aims to map the various data journeys of an individual datum through this big data environment, and to uncover the socio-cultural values that shape the data and processes involved in data production, transformation, use and reuse. We then illustrate how we will disseminate our findings through the design of a forthcoming interactive web site, which presents the data journeys using a path/map metaphor, enabling the exploration of four interconnected case studies and several cross-cutting themes, in a way that is both flexible for the user and expandable, as the research progresses further.ye
