Publishing your data• There are roughly three ways to publish research

data: – In a data archive as an independent object– As a description of a data set in a data paper / data journal– As a component in a web of relations, so called “Scientific

Publication Package” (SPP)

Data Journal• An online-only journal,

the Geoscience Data Journal, publishes short data papers cross-linked to, and citing, datasets that have been deposited in approved data centres.

www.geosciencedata.com

• A data paper describes a dataset, giving details of its collection, processing, software, file formats etc, without the requirement of novel analyses or ground breaking conclusions. It allows the reader to understand the when, how and why data was collected and what the data-product is.

Article:More information, such as:

Data production methods1. Data acquisitionSpecification of IDRA, (IRCTR Drizzle Radar)

2. Data processingpolarimetric weather radar observables, i.e. differential reflectivity, linear depolarization ratio, and differential phase, and the Doppler moments, i.e. Doppler velocity and Doppler spectrum width are computed

3. Data storage

data are processed in real-time and stored in binary format on hard disks placed in the basement of the Cabauw mast. Regularly, the hard disks are broughtto Delft.

4. Dataset location and formatThe IDRA dataset is storedat theDutch 3TU.Datacentrum

5. Dataset use and reuseIDRA data were used so far mainly to study possible improvements of weather radar signal and data processing

Scientific Publication Package

A SPP is a complex, composite digital object which encapsulates a variety of related heterogeneous components.

Like:• Pre-existing data, models, hypotheses or publications• Large datasets generated from experiments, observations and

instruments. These may include: numerical data, survey data, questionnaires, images, video, audio, maps, spectral data, real-time sensor data

• Experimental and instrumental conditions, settings and parametric ranges or constraints

• Assumptions made and criteria applied• Formulas, rules, hypotheses, numerical models, mathematical

functions• Conceptual models - paradigmatic, explanatory information or ideas in

the form of axioms, models and metaphors

Scientific Publication Package

…continued…• Software tools and services – that perform the analysis,

interpretation, transformation, visualization, simulation and modelling of the data. This includes actual source code or executables, applets or links to web services as well as documentation describing the software

• Hardware specifications – the instruments used to generate the data, the instrumental settings, and the computers that execute the analysis, processing, integration and visualization of the data

• Workflows – steps involved in transforming the raw data into knowledge

• Visualizations – 2D, 3D imagery, graphs, tables, charts, diagrams, animations
