2 TERENO Terrestrial Environmental Observatory Managing data in environmental monitoring

3 What is TERENO? TERENO is an infrastructure initiative by the Helmholtz Association to provide an environmental monitoring infrastructure for the scientific community. Construction started in 2008, operation planned for 25 years. 4 regional observatories TERENO Northeast has 8 study sites 32 platforms Approx. 35 M data entries from various sensors More platforms being added The other three regional observatories are of similar scale. 3 | Joining the dots | Jens Klump

4 Regions of high climate vulnerability 4 |  Droughts  Heat waves  Floods  Winter storms  Loss of biodiversity  Landsides Regions of high vulnerability From: Rüdiger Glaser (2008) Klimageschichte Mitteleuropas 1200 Jahre Wetter, Klima, Katastrophen Joining the dots | Jens Klump

5 TERENO Regional Observatories 5 |  Northeastern German Lowland Observatory Coordination: GFZ  Harz / Central German Lowland Observatory Coordination: UFZ  Eifel / Lower Rhine Valley Observatory Coordination: FZJ  Bavarian Alps / pre-Alps Observatory Coordination: HMUG und KIT Joining the dots | Jens Klump

6 TERENO Research Goals 6 | Atmosphere Terrestrial Biosphere Terrestrial Hydrosphere & Pedosphere Investigate interactions and feedbacks between different compartments: Bridging the gap between measure-ment, model and management: Joining the dots | Jens Klump

12 Looking Ahead: Future Directions Data Driven Research in the Geological Sciences

13 Identifiers for software Similar to data an specimens, also software should be identifiable in a persistent way. Establish the missing link between papers and data. Make software recognisable as a scientific achievement. Make science more transparent and reproducible. Simply assigning DOI to software is a good start but might not be good enough. Again, we encounter the question of identity (version) and location (repository). 13 | Joining the dots | Jens Klump

14 Managing Data from Sensor Networks 14 | Joining the dots | Jens Klump

15 Working with very large data sets Some data sets are too large to be inspected in detail, or even to be loaded on a desktop PC. Example: How would one check three years of meteorological radar data for anomalies? Data mining today mainly involves numerical and textual media. Processing will have to move from the desk top to the cloud for large data sets. 15 | Joining the dots | Jens Klump

16 Linked Data 1.Use URIs to denote things. 2.Use HTTP URIs so that these things can be referred to and looked up ("dereferenced") by people and user agents. 3.Provide useful information about the thing when its URI is dereferenced, leveraging standards such as RDF, SPARQL. 4.Include links to other related things (using their URIs) when publishing data on the Web. 16 | Joining the dots | Jens Klump

17 Summary Persistent identifiers allow us to publish, cite, identify data, specimens and software. Data publication is now becoming more common. The principles of data identification can also be used with materials (e.g. IGSN) and software. Future publications might consist of elements linked by identifiers: Interpretation (“Paper”) Data Materials Software and workflows More and more data repositories offer API based on linked data. Future data “publication” will also cater both for people and user agents. 17 | Joining the dots | Jens Klump
