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.
