Research Infrastructures (RIs) play a critical role by enabling excellent science by observing the environment and providing scientific data. Environmental data such as carbon, water and energy fluxes are fundamental to understanding ecosystem processes and their feedback to atmospheric boundary layers' dynamics. These fluxes and their environmental drivers are captured by ‘best community practices’, instruments and procedures operated by most environmental RIs. Different data representations currently pose barriers to semantic data interoperability and data exchange across regional-to-continent-to-global observation programs. The metadata of flux data (e.g., essential variables, UoM, instruments, and platforms) must be in a form that can be processed by machines with minimal human intervention, in the spirit of the FAIR principles. The partnership among RIs to standardize the semantic descriptions of flux data is essential to facilitate national and international research collaborations and enable national- to global-scale problem-solving. This effort is in line with one of the goals of the Global Ecosystem Research Infrastructure (GERI), and will further develop existing work the standardisation of flux data (e.g., by FLUXNET).
The objectives of this BoF session are to:
Bring together different RIs that are part of FLUXNET networks and GERI to review progress made and identify barriers and opportunities towards establishing the semantic descriptions of flux data (i.e., variable names, variable attributes);
Identify the gaps and opportunities to enable interoperable flux data through semantic-based solutions;
Explore ways to continue the partnership among the RIs to enable flux-data interoperability, e.g., establish an Interest Group of RDA.
Invited and Lightning talks about semantic interoperability work undertaken in the Flux community
(Invited Talk) A short introduction to FLUXNET (and the data issues challenges we set out to solve…) : Dario Papale, Claudio D’onofrio, Deb Agarwal, Daniella Christianson, Christopher Florian, David Durden, Stefan Metzger
Management and Interoperability of TERENO Flux Data : Ralf Kunkel
TERN Ecosystem Process Flux Tower Data : Peter Isaac
Flux Data Standards : Deb Agarwal
Flux Data within the South African Environmental Observation Network (SAEON) and the associated EFTEON Research Infrastructure : Gregor Feig, Bryan McAlister
Group Discussions and Feedback
The representatives of the FLUXNET networks and GERI (e.g., TERN, ICOS, NEON, AmeriFlux, TERENO, SAEON and NEON) will introduce their work on flux-data interoperability and associated impediments. The group discussion will focus on the following topics and be encouraged through an interactive discussion (Miro board).
Existing initiatives on interoperability of flux data
Standard representation and management of variables, instruments and platform
Motivation of sharing data between RIs
Critical concepts of semantics and semantic ontologies in flux data integration
Use cases on the applications of flux data integration
Identify prototyping and test-bed activities
Establish ‘next steps’
The discussion will also delve into alignment with related RDA IGs/WGs.
