GEM-ULTIMA Forum

The GEM-ULTIMA Forum is held annually during the mini-GEM Workshops in December. The Forum is organized jointly by GEM and the Ultra Large Terrestrial International Magnetometer Array (ULTIMA). At the Forum participants discuss all topics about ground-based magnetometers, including the operation of magnetometer stations, data distribution, and research using ground-based magnetometer data.

Below are the presentations made at the GEM-ULTIMA Forum.
