EXPLORING THE EARTH SYSTEM DATA CUBE

1 EXPLORING THE EARTH SYSTEM DATA CUBE A Workshop exploring trajectories, outliers & extreme events, and causal relations in the emerging multidimensional Earth system data cube DATE AND LOCATION: Max-Planck-Institute for Biogeochemistry, Jena, Germany Date: Nov (informal arrival dinner on Nov. 25.), 2015 BACKGROUND: Across Europe (and elsewhere), many projects and scientists are working in parallel on the question of how to tap into the potential of a simultaneous exploration of multiple Earth Observations (EOs). New missions and reprocessing of existing data archives confront scientists with an unprecedented amount of data simultaneously monitoring the land surface from multiple perspectives. The CAB-LAB project aims to support the exploration of multiple ESA- EOs (together with other relevant data streams) to better characterize the trajectories of land ecosystem changes. This endeavour requires developing and applying novel, ideally robust and generally multivariate statistical methods and data mining tools to explore the emerging high dimensional Earth system data cube. The focal topic for this workshop is co-interpreting EOs for their capacity to extract longer-term transformations, detect impacts of extreme anomalies, and ideally also discover causal relations affecting land ecosystems. This path into new approaches is a pressing scientific challenge, currently being tackled on many fronts. Participants are invited from across this diverse community to explore the issues together. The ultimate goals is achieving a better understanding of the trajectory of land-surface processes and their relation to other components of the Earth system in particular, the atmosphere and hydrological cycle, and the role of humans. In this context, the CAB-LAB team will also introduce the Earth System Data Cube that it is developing, together with prototypes of mechanisms to empower the scientific community to explore EOs towards a better understanding of landatmosphere interactions.

2 AIMS: Bringing together scientists of different disciplines i.e. o Environmental scientists actively working on (the exploration of EOs for) detecting, interpreting, and attributing extremes and anomalies in land-surface processes. o Statistical and mathematical scientists actively working on developing novel approaches to deal with high-dimensional data i.e. time series to map transient changes, detect multivariate extremes, novelty data constellations, or developing statistical attribution schemes or new ideas on causal inference. o The interested community that aims at exploring the emerging Earth system data cube for different purposes from an Earth system, societal perspective, or methodological perspective. Exchanging experiences, initiating collaborations, and maximizing synergies amongst the European scientists interested in the methodological devolvement s or applications for exploring the suite of ESA data. Gaining an overview of European research activities exploring the suite of EOs in tandem, beyond univariate/disciplinary approaches. Identifying common strategic scientific goals for the coming years, where collaboration could lead to an added value for all participants, i.e. developing a scientific roadmap. Hence, the workshop will help identifying where ESA support can strength other research initiatives, by tailoring its products and data analytic toolkit to the needs of the community.

3 WORKSHOP STRUCTURE We have slots for very few people to present their ideas and we aimed at getting a nice overview from data products, methodological advances to scientific applications. The reason for not giving the word to all is that we primarily intend to discuss and work towards a Scientific Roadmap. However, please bring along short presentations from 1-3 slides to present your ideas wherever appropriate in the middle of the workshop. Ideally, the results of the workshop will be summarized in a outlook paper that will be published together in two forms: A: scientific paper and B: letter to the scientific community a Scientific Roadmap that should inform the ESA, ileaps and other relevant institutions about our finding and perspectives.
