CARE-C research facilities will generate a mass of environmental data from observations and modelling that will need automated processing according to quality control protocols (some of them performed in near real time), curation, and storage for further exploitation by different R&D departments and third parties. Based on the successful “SmartSMEAR” system (involving near real-time data and on-line visualisations), and the SMEAR data web portal, DAC will be established providing well-documented open access to observational data and related process chains and flows.
