TERENO Terrestrial Environmental Observatory

Managing data in environmental monitoring

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.

TERENO Research Goals

Investigate interactions and feedbacks between different compartments: Bridging the gap between measure-ment, model and management:

Atmosphere Terrestrial Biosphere Terrestrial Hydrosphere & Pedosphere

Looking Ahead: Future Directions

Data Driven Research in the Geological Sciences

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).

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.

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.

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.
