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.

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).
