DMI Geophysical Data Center Functions

The geophysical data center functions conducted by DMI fall in four different categories. Each of these data center functions has its own "Rules of the Road" for data exchange.

World Data Center C1 for Geomagnetic Data

The world data center (WDCC1) function implies, that the DMI is holding a comprehensive series of data supplied from a worldwide net of geomagnetic observatories. These data are available for scientific use through WDCC1. The rules for their use are defined by the international world data center agreements. Information on the appropriate institution(s) to acknowledge for providing the data are supplied with the data sets.

Oersted Science Data Center

The Oersted Science Data Center (OSDC) is operated at DMI to serve the Co-Investigator community formed around the danish geomagnetic satellite "Oersted". The rules of the road for Oersted data exchange are defined by the Oersted Steering Committee and made public in communications to the Oersted Science Community.

Data Center for collaborative ground-based geophysical observations

In collaborative projects to conduct ground-based observations of geophysical parameters, the "rules of the road" for data exchange are defined in each case by agreement between DMI and the partner(s) of the collaborative project. This category of observations comprise the digisonde observations conducted at Greenland (PI: Phillips Lab., USA), the Incoherent Scatter Radar (ISR) observations conducted from Sondrestrom, Greenland (PI: SRI International (for NSF), USA), the "Magnetometer Array on Greenland Ice Cap" (MAGIC) project (PI: University of Michigan, USA), and the Imaging Riometer observations from Greenland and Svalbard (PI: DMI).

Data Center for DMI ground-based geophysical observations

This category of observations, where DMI has the sole responsibility for the data collection and provides the ressources needed to conduct the observations, comprise the data from the magnetometer arrays at Greenland Eastcoast and Westcoast, and from the normal-beam riometer array. For these data the following "rules of the road" apply:

"These geophysical data are the intellectual property of the Danish Meteorological Institute (DMI). They may be freely used for the purpose of illustration, for teaching, and for non-commercial scientific research provided that the source (observations manager/DMI) is acknowledged and that the following guidelines are duly considered:

1. In general, geophysical data are supplied from DMI only as part of a scientific collaboration involving mutual data exchange or joint research efforts.

2. Any substantial use of DMI data should be discussed at an early stage with the responsible scientist at DMI in order to clarify matters of quality and interpretation of data and potential co-authorship in publication efforts.

3. Data made available by DMI should not be passed on to other users. Requests for DMI data from third parties should be addressed directly to DMI.

4. The responsible DMI scientist should be given the possibility to comment on any interpretation based on these data prior to publication (on this basis the responsible DMI scientist will decide whether co-authorship is appropriate). Copies of published reports and papers using the data should be sent to DMI to maintain here a record on their use.
