THEMIS Level 2 GMAG file info:

Ground Magnetometer (GMAG) The Level 2 files include magnetic field data from 106 different sites across the northern hemisphere and two stations in Antarctica. There are 22 official THEMIS GMAG stations in the Northern United States and Canada. Ten of these systems are installed with the Ground-Based Observatory (GBO) systems for THEMIS. Twelve are installed in schools and are part of the THEMIS Education and Public Outreach (E/PO) program. These magnetometers, known as the E/PO magnetometers, are the exact same type of magnetometer as those built for the GBOs. These GMAGs measure the magnetic field with 0.01 nT resolution at 2 samples/second. Units are nanotesla. Also included in the L2 distribution are stations from the University of Alaska, the University of Alberta, the MACCS project at Augsburg College, the University of Athabasca, the Technical University of Denmark, the Tromsø Geophysical University in Norway, the US Geological Survey, the Geological Survey of Canada, the Geological Survey of Sweden (SGU), the Leirvogur Magnetic Observatory in Iceland, AARI in Russia, and the PENGUIn network in Antarctica.
