US Ground Magnetometer Board

This wiki page and related ground magnetometer board meetings are part of a community driven effort to (1) review operations/status/performance of all US-funded ground magnetometer arrays, (2) discuss priorities for future ground magnetometer locations in consultation with the wider community including USGS/ULTIMA/NSF, (3) transition towards a Class-II facility/DASI operations model as recommended by the 2015-2016 NSF Geospace Portfolio Review, (4) facilitate the production and dissemination of high level data products that support scientific investigations, spacecraft missions, modeling efforts, and space weather forecasts. For more information about the current state and future of ground magnetometer networks in support of space weather monitoring and research, see this article in Space Weather.

Digital Object Identifiers for Ground Magnetometer Data

Digital Object Identifiers (DOI) allow authors to cite data products just as they refer to papers. This is becoming a requirement of many journals, as it assures that the specific data used in a publication are findable and accessible. The DOI provides a permanent identifier (PID) for the data, remaining unchanged even if the data are moved to another archive. The "creators" (authors) of the data must link the DOI to a "landing page" that provides details about the data and methods for accessing them. Our group recommends that each ground magnetometer network generate DOIs for their datasets, at minimum one DOI for their original measurements (i.e., before filtering and other types of processing are performed).

As a member of the DataCite organization, NASA Heliophysics (HP) can "mint" DOIs for ground magnetometer datasets. NASA HP is providing an easy means to assign DOIs to datasets using the HP Digital Resource Registry (HDRR) by providing landing pages for datasets based on their "SPASE" resource descriptions. As an example, any users of NASA's OMNI dataset can now use https://doi.org/10.48322/1shr-ht18 for the hourly dataset, and other DOIs for other sets, discoverable by a search with the Heliophysics Data Portal (HDP; https://heliophysicsdata.gsfc.nasa.gov; look for "omni" in the "observatory" entry at the left). More details for DOI initiation for resources in the HDP can be found here. For further information, and especially to start the process of registering DOIs, contact James Weygand (jweygand@igpp.ucla.edu or jweygand@epss.ucla.edu).

As noted above, a SPASE resource description is required for each magnetometer dataset to mint a DOI. Here's an example for the MACCS magnetometer network 5s measurements.

2019 GEM workshop meeting

The ground magnetometer advisory board was formed in 2016 as a community driven effort to (1) review operations/status/performance of all US-funded ground magnetometer arrays, (2) discuss priorities for future ground magnetometer locations in consultation with the wider community including USGS/ULTIMA/NSF, (3) transition towards a Class-II facility/DASI operations model as recommended by the 2015-2016 NSF Geospace Portfolio Review, (4) facilitate the production and dissemination of high level data products that support scientific investigations, spacecraft missions, modeling efforts, and space weather forecasts.

We invite the GEM community to attend our meeting on Monday, June 24 at 1:30 PM, where we’ll discuss updates on all the above items. Later this year, we’ll add new members to the advisory board who either operate ground magnetometers or use magnetometer data to support their scientific investigations and/or space weather monitoring efforts. If you’re interested in learning more about this opportunity, please attend this GEM meeting or contact Mike Hartinger (mdhartin@vt.edu).
