Data policy for data sets from various sources: recent developments in the Integrated Carbon Observation System (ICOS)

Fluxnet is facing a transition from single PI and project engagement to a cooperation of infrastructures such as ICOS, Ameriflux, NEON, Chinaflux or TERN. Each of these infrastructures has developed its own data life cycle, data license and data policy which will have implications on future cooperation within Fluxnet and other global data integration efforts such as e.g. SOCAt in the ocean community. This presentation will introduce into the recent developments of the ICOS data policy and show perspectives for future cooperation in global networks. The challenge in developing the ICOS data policy has been to find the best compromise between optimized access for users and sufficient visibility and acknowledgement of data providers. ICOS data will be provided under the Creative Commons 4.0 BY license. ICOS data will be provided through the ICOS Carbon Portal. Data usage will be absolutely unrestricted. Data have only to be attributed as ICOS data. With the attribution ICOS will provide a persistent identifier (pid, sometimes also nominated as digial object identifier, doi) that will direct to a landing page where data provider and if necessary also funding organisations are identified. In cooperation with other environmental research infrastructures in the framework of the European cluster project ENVRIplus and the Research Data Alliance (RDA) the ICOS Carbon Portal is currently developing a data citation system. This includes developing recommendations for data citation of integrated data sets from different sources.
