Shom magnetic reference stations

The "Magnetic Stations" product contains measurements from magnetic reference stations deployed by the French Hydrographic and Oceanographic Service (SHOM) near marine magnetic survey areas. Measurement files are available by station and by year. These magnetic reference measurements correct marine measurements for diurnal and high-frequency variations in the Earth's magnetic field.
