NOA currently operates ENIGMA (HellENIc GeoMagnetic Array), an array of 3 ground-based magnetometer stations located in Trikala (Klokotos), Attiki (Dionysos) and Lakonia (Velies), Greece. ENIGMA provides measurements for the study of geomagnetic pulsations, resulting from the solar wind- magnetosphere coupling. Ground-based magnetometers have proven to be the workhorse of magnetosphere-ionosphere coupling physics. They enable effective remote sensing of geospace dynamics and therefore their importance in space weather monitoring and research is indisputable. ENIGMA is the first magnetometer station array that has ever operated in Greece and within a few years of operation has succeeded in becoming a SuperMAG contributor. SuperMAG (http://supermag.jhuapl.edu/) is a worldwide collaboration of organizations and national agencies that currently operate more than 300 ground-based magnetometers. SuperMAG provides easy access to validated ground magnetic field perturbations in the same coordinate system, identical time resolution and with a common baseline removal approach.

The purpose of SuperMAG is enable scientists, teachers, students and the general public to have easy access to measurements of the Earth’s magnetic field.
